abstract = {In the era of mobile imaging, the quality of document photos captured by smartphones often suffers due to adverse lighting conditions. Traditional document analysis and optical character recognition systems encounter difficulties with images that have not been effectively binarized, particularly under challenging lighting scenarios. This paper introduces a novel adaptive binarization algorithm optimized for such difficult lighting environments. Unlike many existing methods that rely on complex machine learning models, our approach is streamlined and machine-learning free, designed around integral images to significantly reduce computational and coding complexities. This approach enhances processing speed and improves accuracy without the need for computationally expensive training procedures. Comprehensive testing across various datasets, from smartphone-captured documents to historical manuscripts, validates its effectiveness. Moreover, the introduction of versatile output modes, including color foreground extraction, substantially enhances document quality and readability by effectively eliminating unwanted background artifacts. These enhancements are valuable in mobile document image processing across industries that prioritize efficient and accurate document management, spanning sectors such as banking, insurance, education, and archival management.},

abstract = {In histopathology, histologic elements are not randomly located across an image but organize into structured patterns. In this regard, classification tasks or feature extraction from histology images may require context information to increase performance. In this work, we explore the importance of keeping context information for a cell classification task on Hematoxylin and Eosin (H&E) scanned whole slide images (WSI) in colorectal cancer. We show that to differentiate normal from malignant epithelial cells, the environment around the cell plays a critical role. We propose here an image augmentation based on gamma variations to guide deep learning models to focus on the object of interest while keeping context information. This augmentation method yielded more specific models and helped to increase the model performance (weighted F1 score with/without gamma augmentation respectively, PanNuke: 99.49 vs 99.37 and TCGA: 91.38 vs. 89.12, p<0.05). }

abstract = {In digital pathology, cell-level tissue analyses are widely used to better understand tissue composition and structure. Publicly available datasets and models for cell detection and classification in colorectal cancer exist but lack the differentiation of normal and malignant epithelial cells that are important to perform prior to any downstream cell-based analysis. This classification task is particularly difficult due to the high intra-class variability of neoplastic cells. To tackle this, we present here a new method that uses graph-based node classification to take advantage of both local cell features and global tissue architecture to perform accurate epithelial cell classification. The proposed method demonstrated excellent performance on F1 score (PanNuke: 1.0, TCGA: 0.98) and performed significantly better than conventional computer vision methods (PanNuke: 0.99, TCGA: 0.92).}

abstract = {On-line handwritten character segmentation is often associated with handwriting recognition and even though recognition models include mechanisms to locate relevant positions during the recognition process, it is typically insufficient to produce a precise segmentation. Decoupling the segmentation from the recognition unlocks the potential to further utilize the result of the recognition. We specifically focus on the scenario where the transcription is known beforehand, in which case the character segmentation becomes an assignment problem between sampling points of the stylus trajectory and characters in the text. Inspired by the k-means clustering algorithm, we view it from the perspective of cluster assignment and present a Transformer-based architecture where each cluster is formed based on a learned character query in the Transformer decoder block. In order to assess the quality of our approach, we create character segmentation ground truths for two popular on-line handwriting datasets, IAM-OnDB and HANDS-VNOnDB, and evaluate multiple methods on them, demonstrating that our approach achieves the overall best results.},

abstract = {This paper presents an innovative methodology for enhancing energy efficiency assessment procedures in the built environment, with a focus on the Switzerland's Energy Strategy 2050. The current methodology necessitates intensive expert surveys, leading to substantial time and cost implications. Also, such a process can't be scaled to a large number of buildings. Using machine learning techniques, the estimation process is augmented and exploit open data resources. Utilizing a robust dataset exceeding 70'000 energy performance certificates (CECB), the method devises a two-stage ML approach to forecast energy performance. The first phase involves data reconstruction from online repositories, while the second employs a regression algorithm to estimate the energy efficiency. The proposed approach addresses the limitations of existing machine learning methods by offering finer prediction granularity and incorporating readily available data. The results show a commendable degree of prediction accuracy, particularly for single-family residences. Despite this, the study reveals a demand for further granular data, and underlines privacy concerns associated with such data collection. In summary, this investigation provides a significant contribution to the enhancement of energy efficiency assessment methodologies and policy-making.}

In this paper, we introduce the Bullinger dataset for writer adaptation, which is based on the Heinrich Bullinger letter collection from the 16th century, using a subset of 3,622 annotated letters (about 1.2 million words) from 306 writers. We provide baseline results for handwriting recognition with modern recognizers, before and after the application of standard techniques for supervised adaptation of frequent writers and self-supervised adaptation of non-frequent writers.},

volume = {47},
number = {3},
abstract = {In order to access the rich cultural heritage conveyed in Vietnamese steles, automatic reading of stone engravings would be a great support for historians, who are analyzing tens of thousands of stele images. Approaching the challenging problem with deep learning alone is difficult because the data-driven models require large representative datasets with expert human annotations, which are not available for the steles and costly to obtain. In this article, we present a hybrid approach to spot keywords in stele images that combines data-driven deep learning with knowledge-based structural modeling and matching of Chu Nom characters. The main advantage of the proposed method is that it is annotation-free, i.e. no human data annotation is required. In an experimental evaluation, we demonstrate that keywords can be successfully spotted with a mean average precision of more than 70% when a single engraving style is considered.}

abstract = {Colon resection is often the treatment of choice for colorectal cancer (CRC) patients. However, especially for minimally invasive cancer, such as pT1, simply removing the polyps may be enough to stop cancer progression. Different histopathological risk factors such as tumor grade and invasion depth currently found the basis for the need for colon resection in pT1 CRC patients. Here, we investigate two additional risk factors, tumor budding and lymphocyte infiltration at the invasive front, which are known to be clinically relevant. We capture the spatial layout of tumor buds and T-cells and use graph-based deep learning to investigate them as potential risk predictors. Our pT1 Hotspot Tumor Budding T-cell Graph (pT1-HBTG) dataset consists of 626 tumor budding hotspots from 575 patients. We propose and compare three different graph structures, as well as combinations of the node labels. The best-performing Graph Neural Network architecture is able to increase specificity by 20% compared to the currently recommended risk stratification based on histopathological risk factors, without losing any sensitivity. We believe that using a graph-based analysis can help to assist pathologists in making risk assessments for pT1 CRC patients, and thus decrease the number of patients undergoing potentially unnecessary surgery. Both the code and dataset are made publicly available.}

Pre-implemented tasks such as segmentation and classification can be easily used or customized. It is also easy to create one’s own tasks with the benefit of powerful modules for loading data, even large data sets, and different forms of ground truth. The applications conducted have demonstrated time savings for the programming of a document analysis task, as well as for different scenarios such as pre-training or changing the architecture. Thanks to its data module, the framework also allows to reduce the time of model training significantly.},

abstract = {Automatic handwriting recognition for historical documents is a key element for making our cultural heritage available to researchers and the general public. However, current approaches based on machine learning require a considerable amount of annotated learning samples to read ancient scripts and languages. Producing such ground truth is a laborious and time-consuming task that often requires human experts. In this paper, to cope with a limited amount of learning samples, we explore the impact of using synthetic text line images to support the training of handwriting recognition systems. For generating text lines, we consider lineGen, a recent GAN-based approach, and for handwriting recognition, we consider HTR-Flor, a state-of-the-art recognition system. Different meta-learning strategies are explored that schedule the addition of synthetic text line images to the existing real samples. In an experimental evaluation on the well-known Bentham dataset as well as the newly introduced Bullinger dataset, we demonstrate a significant improvement of the recognition performance when combining real and synthetic samples.},

A lot of these problems on Büchi automata are computationally hard, raising the question if a learning-based data-driven analysis might be more efficient than using traditional algorithms. Since Büchi automata can be represented by graphs, graph neural networks are a natural choice for such a learning-based analysis. In this paper, we demonstrate how graph neural networks can be used to reliably predict basic properties of Büchi automata when trained on automatically generated random automata datasets.}

abstract = {Designing efficient interconnects to support high-bandwidth and low-latency communication is critical toward realizing high performance computing (HPC) and data center (DC) systems in the exascale era. At extreme computing scales, providing the requisite bandwidth through overprovisioning becomes impractical. These challenges have motivated studies exploring reconfigurable network architectures that can adapt to traffic patterns at runtime using optical circuit switching. Despite the plethora of proposed architectures, surprisingly little is known about the relative performances and trade-offs among different reconfigurable network designs. We aim to bridge this gap by tackling two key issues in reconfigurable network design. First, we study how cost, power consumption, network performance, and scalability vary based on optical circuit switch (OCS) placement in the physical topology. Specifically, we consider two classes of reconfigurable architectures: one that places OCSs between top-of-rack (ToR) switches---ToR-reconfigurable networks (TRNs)---and one that places OCSs between pods of racks---pod-reconfigurable networks (PRNs). Second, we tackle the effects of reconfiguration frequency on network performance. Our results, based on network simulations driven by real HPC and DC workloads, show that while TRNs are optimized for low fan-out communication patterns, they are less suited for carrying high fan-out workloads. PRNs exhibit better overall trade-off, capable of performing comparably to a fully non-blocking fat tree for low fan-out workloads, and significantly outperform TRNs for high fan-out communication patterns.},

We first applied a preprocessing and a feature extraction stage before using five Machine Learning algorithms, allowing us to compare them. Ensemble learning algorithms such as Random Forest and Gradient Boosting have the best performance, with a Sensitivity and Specificity both close to 99%. Our contribution is: a multi-class classification approach for fall detection combined with a study of the effect of the sensors’ sampling rate on the performance of the FDS. Our multi-class classification approach splits the fall into three phases: pre-fall, impact, post-fall. The extension to a multi-class problem is not trivial and we present a well-performing solution. We experimented sampling rates between 1 and 200 Hz. The results show that, while high sampling rates tend to improve performance, a sampling rate of 50 Hz is generally sufficient for an accurate detection.},

The theory has been confirmed in a large number of experimental evaluations, achieving a high reconstruction quality when compared with observed trajectories and providing pertinent features for biomedical applications as well as biometric identification. So far, the Kinematic Theory has focused on one-dimensional movements with the Delta-Lognormal model and on two-dimensional movements with the Sigma-Lognormal model. In this chapter, we present a model for movements in three dimensions, which naturally extends the Sigma-Lognormal approach. We evaluate our method on two action recognition datasets and an air-writing dataset, demonstrating a high reconstruction quality for modelling rapid 3D movements in all cases. }

abstract = {Allele frequencies vary across populations and loci, even in the presence of migration. While most differences may be due to genetic drift, divergent selection will further increase differentiation at some loci. Identifying those is key in studying local adaptation, but remains statistically challenging. A particularly elegant way to describe allele frequency differences among populations connected by migration is the F-model, which measures differences in allele frequencies by population specific FST coefficients. This model readily accounts for multiple evolutionary forces by partitioning FST coefficients into locus and population specific components reflecting selection and drift, respectively. Here we present an extension of this model to linked loci by means of a hidden Markov model (HMM), which characterizes the effect of selection on linked markers through correlations in the locus specific component along the genome. Using extensive simulations we show that the statistical power of our method is up to two-fold that of previous implementations that assume sites to be independent. We finally evidence selection in the human genome by applying our method to data from the Human Genome Diversity Project (HGDP).},

The main advantages of ML are in the ability to (1) capture non-linear phenomena, (2) adapt to many different processes without human intervention and (3) learn incrementally and improve over time. In this paper, we take the perspective of IT system architects and analyse the implications of the inclusion of ML components into a traditional anomaly detection systems. Through a prototype that we deployed for chemical reactors, our findings are that such ML components are impacting drastically the architecture of classical alarm systems. First, there is a need for long-term storage of the data that are used to train the models. Second, the training and usage of ML models can be CPU intensive and may request using specific resources. Third, there is no single algorithm that can detect machine errors. Fourth, human crafted alarm rules can now also include a learning process to improve these rules, for example by using active learning with a human-in-the-loop approach. These reasons are the motivations behind a microservice-based architecture for an alarm system in industrial machinery.}

As Swiss German is, for now, a predominantly spoken language, there is a significant variation in the written forms, even between speakers of the same dialect. To alleviate the uncertainty associated with this diversity, we complement the pairs of Swiss German - High German words with the Swiss German phonetic transcriptions (SAMPA). This dictionary becomes thus the first resource to combine large-scale spontaneous translation with phonetic transcriptions. Moreover, we control for the regional distribution and insure the equal representation of the major Swiss dialects. The coupling of the phonetic and written Swiss German forms is powerful. We show that they are sufficient to train a Transformer-based phoneme to grapheme model that generates credible novel Swiss German writings. In addition, we show that the inverse mapping - from graphemes to phonemes - can be modeled with a transformer trained with the novel dictionary. This generation of pronunciations for previously unknown words is key in training extensible automated speech recognition (ASR) systems, which are key beneficiaries of this dictionary.},

In order to better automate this process for sustained excavations, we are exploring the possibility of approximating key values using a machine learning (ML) model instead of calculating them with time-consuming numerical simulations. After demonstrating in our previous work that this approach works for simple use cases, we show in this paper that this method can be enhanced to adapt to complex real-world supported excavations. We have improved our ML model compared to our previous work by using a convolutional neural network (CNN) model, coding the excavation configuration as a set of layers of fixed height containing the soil parameters as well as the geometry of the walls and struts. The system is trained and evaluated on a set of synthetically generated situations using numerical simulation software. To validate this approach, we also compare our results to a set of 15 real-world situations in a t-SNE. Using our improved CNN model we could show that applying machine learning to predict the output of numerical simulation in the domain of geotechnical engineering not only works in simple cases but also in more complex, real-world situations.",

While the overall timing of the proposed approach and its scaling has still to be measured and studied, we demonstrate that, in terms of efficiency and purity, the same physics performance of the LHC tracking algorithms can be achieved. More research will be needed to achieve comparable performance in HL-LHC conditions, as increasing track density decreases the purity of the QUBO track segment classifier.},

However, at the Radio Resource Management (RRM) level, the existing schedulers are rather static being unable to react according to the momentary networking conditions so that the user fairness measure is maximized all time. This paper proposes a dynamic scheduler framework able to parameterize the proportional fair scheduling rule at each Transmission Time Interval (TTI) to improve the user fairness. To deal with the framework complexity, the parameterization decisions are approximated by using the neural networks as non-linear functions. The actor-critic Reinforcement Learning (RL) algorithm is used to learn the best set of non-linear functions that approximate the best fairness parameters to be applied in each momentary state. Simulations results reveal that the proposed framework outperforms the existing fairness adaptation techniques as well as other types of RL-based schedulers.},

In this paper, we study the imbalance between the way certain token pairs are included in data points and others are not. We denote this a token order imbalance (TOI) and we link the partial sequence information loss to a diminished performance of the system as a whole, both in text and speech processing tasks. We then provide a mechanism to leverage the full token order information{---}Alleviated TOI{---}by iteratively overlapping the token composition of data points. For recurrent networks, we use prime numbers for the batch size to avoid redundancies when building batches from overlapped data points. The proposed method achieved state of the art performance in both text and speech related tasks.",

abstract = {To evaluate the role of constitutive epigenetic changes in normal body cells of BRCA1/BRCA2‐mutation negative patients, we have developed a deep bisulfite sequencing assay targeting the promoter regions of 8 tumor suppressor (TS) genes (BRCA1, BRCA2, RAD51C, ATM, PTEN, TP53, MLH1, RB1) and the estrogene receptor gene (ESR1), which plays a role in tumor progression. We analyzed blood samples of two breast cancer (BC) cohorts with early onset (EO) and high risk (HR) for a heterozygous mutation, respectively, along with age‐matched controls. Methylation analysis of up to 50,000 individual DNA molecules per gene and sample allowed quantification of epimutations (alleles with >50% methylated CpGs), which are associated with epigenetic silencing. Compared to ESR1, which is representative for an average promoter, TS genes were characterized by a very low (< 1%) average methylation level and a very low mean epimutation rate (EMR; < 0.0001% to 0.1%). With exception of BRCA1, which showed an increased EMR in BC (0.31% vs. 0.06%), there was no significant difference between patients and controls. One of 36 HR BC patients exhibited a dramatically increased EMR (14.7%) in BRCA1, consistent with a disease‐causing epimutation. Approximately one third (15 of 44) EO BC patients exhibited increased rates of single CpG methylation errors in multiple TS genes. Both EO and HR BC patients exhibited global underexpression of blood TS genes. We propose that epigenetic abnormalities in normal body cells are indicative of disturbed mechanisms for maintaining low methylation and appropriate expression levels and may be associated with an increased BC risk. What's new? Cancer can change patterns of DNA methylation, with widespread loss of methylation but also localized increases in methylation. Here, the authors analyzed blood cells, looking for differences in methylation between breast cancer patients and healthy persons. They developed a deep bisulfite sequencing assay to specifically test the promoter regions of 8 tumor suppressor genes, plus the estrogen receptor gene, along with reduced tumor suppressor gene expression. They found that breast cancer patients showed increased methylation changes in multiple tumor suppressor genes, reduced tumor suppressor gene expression. Thus, epigenetic abnormalities could indicate disruptions in the mechanisms that maintain proper methylation, and could signal increased tumor risk.}

abstract={Dominated by delay-sensitive and massive data applications, radio resource management in 5G access networks is expected to satisfy very stringent delay and packet loss requirements. In this context, the packet scheduler plays a central role by allocating user data packets in the frequency domain at each predefined time interval. Standard scheduling rules are known limited in satisfying higher quality of service (QoS) demands when facing unpredictable network conditions and dynamic traffic circumstances. This paper proposes an innovative scheduling framework able to select different scheduling rules according to instantaneous scheduler states in order to minimize the packet delays and packet drop rates for strict QoS requirements applications. To deal with real-time scheduling, the reinforcement learning (RL) principles are used to map the scheduling rules to each state and to learn when to apply each. Additionally, neural networks are used as function approximation to cope with the RL complexity and very large representations of the scheduler state space. Simulation results demonstrate that the proposed framework outperforms the conventional scheduling strategies in terms of delay and packet drop rate requirements.},

abstract = "Purpose
To test the hypothesis that contact lens sensor (CLS)-based 24-hour profiles of ocular volume changes contain information complementary to intraocular pressure (IOP) to discriminate between primary open-angle glaucoma (POAG) and healthy (H) eyes.
Design
Development and evaluation of a diagnostic test with machine learning.
Methods
Subjects: From 435 subjects (193 healthy and 242 POAG), 136 POAG and 136 age-matched healthy subjects were selected. Subjects with contraindications for CLS wear were excluded. Procedure: This is a pooled analysis of data from 24 prospective clinical studies and a registry. All subjects underwent 24-hour CLS recording on 1 eye. Statistical and physiological CLS parameters were derived from the signal recorded. CLS parameters frequently associated with the presence of POAG were identified using a random forest modeling approach. Main Outcome Measures: Area under the receiver operating characteristic curve (ROC AUC) for feature sets including CLS parameters and Start IOP, as well as a feature set with CLS parameters and Start IOP combined.
Results
The CLS parameters feature set discriminated POAG from H eyes with mean ROC AUCs of 0.611, confidence interval (CI) 0.493–0.722. Larger values of a given CLS parameter were in general associated with a diagnosis of POAG. The Start IOP feature set discriminated between POAG and H eyes with a mean ROC AUC of 0.681, CI 0.603–0.765. The combined feature set was the best indicator of POAG with an ROC AUC of 0.759, CI 0.654–0.855. This ROC AUC was statistically higher than for CLS parameters or Start IOP feature sets alone (both P < .0001).
Conclusions
CLS recordings contain information complementary to IOP that enable discrimination between H and POAG. The feature set combining CLS parameters and Start IOP provide a better indication of the presence of POAG than each of the feature sets separately. As such, the CLS may be a new biomarker for POAG."

abstract={Expression Templates is a technique allowing to write linear algebra code in C++ the same way it would be written on paper. It is also used extensively as a performance optimization technique, especially as the Smart Expression Templates form which allows for even higher performance. It has proved to be very efficient for computation on a Central Processing Unit (CPU). However, due to its design, it is not easily implemented on a Graphics Processing Unit (GPU). In this paper, we devise a set of techniques to allow the seamless evaluation of Smart Expression Templates on the GPU. The execution is transparent for the user of the library which still uses the matrices and vector as if it was on the CPU and profits from the performance and higher multi-processing capabilities of the GPU. We also show that the GPU version is significantly faster than the CPU version, without any change to the code of the user.},

abstract = {This study presents a novel approach for Arabic video text recognition based on recurrent neural networks. In fact, embedded texts in videos represent a rich source of information for indexing and automatically annotating multimedia documents. However, video text recognition is a non-trivial task due to many challenges like the variability of text patterns and the complexity of backgrounds. In the case of Arabic, the presence of diacritic marks, the cursive nature of the script and the non-uniform intra/inter word distances, may introduce many additional challenges. The proposed system presents a segmentation-free method that relies specifically on a multi-dimensional long short-term memory coupled with a connectionist temporal classification layer. It is shown that using an efficient pre-processing step and a compact representation of Arabic character models brings robust performance and yields a low-error rate than other recently published methods. The authors’ system is trained and evaluated using the public AcTiV-R dataset under different evaluation protocols. The obtained results are very interesting. They also outperform current state-of-the-art approaches on the public dataset ALIF in terms of recognition rates at both character and line levels.},

ABSTRACT = {Recognizing texts in video is more complex than in other environments such as scanned documents. Video texts appear in various colors, unknown fonts and sizes, often affected by compression artifacts and low quality. In contrast to Latin texts, there are no publicly available datasets which cover all aspects of the Arabic Video OCR domain. This paper describes a new well-defined and annotated Arabic-Text-in-Video dataset called AcTiV 2.0. The dataset is dedicated especially to building and evaluating Arabic video text detection and recognition systems. AcTiV 2.0 contains 189 video clips serving as a raw material for creating 4063 key frames for the detection task and 10,415 cropped text images for the recognition task. AcTiV 2.0 is also distributed with its annotation and evaluation tools that are made open-source for standardization and validation purposes. This paper also reports on the evaluation of several systems tested under the proposed detection and recognition protocols.},

abstract = "Abstract Future buildings will more and more rely on advanced Building Management Systems (BMS) connected to a variety of sensors, actuators and dedicated networks. Their objectives are to observe the state of rooms and apply automated rules to preserve or increase comfort while economizing energy. In this work, we advocate for the inclusion of a dedicated system for sensors data storage and processing, based on Big Data technologies. This choice enables new potentials in terms of data analytics and applications development, the most obvious one being the ability to scale up seamlessly from one smart building to several, in the direction of smart areas and smart cities. We report in this paper on our system architecture and on several challenges we met in its elaboration, attempting to meet requirements of scalability, data processing, flexibility, interoperability and privacy. We also describe current and future end-user services that our platform will support, including historical data retrieval, visualisation, processing and alarms. The platform, called BBData - Big Building Data, is currently in production at the Smart Living Lab of Fribourg and is offered to several research teams to ease their work, to foster the sharing of historical data and to avoid that each project develops its own data gathering and processing pipeline."

In this context, Non Intrusive Load Monitoring (NILM) is an approach based on the analysis of the global electricity consumption signal of the habitation. Current NILM solutions are reaching good precision for the identification of electrical devices but at the cost of difficult setups with expensive equipments typically working at high frequency. In this work we propose to use a low-cost and easy to install low frequency sensor for which we improve the performances with an active machine learning strategy. At setup, the system is able to identify some appliances with typical signatures such as a fridge. During usage, the system detects unknown signatures and provides a user-friendly procedure to include new appliances and to improve the identification precision over time."

abstract={In this paper, we present a Conditional Random Field (CRF) model to deal with the problem of segmenting handwritten historical document images into different regions. We consider page segmentation as a pixel-labeling problem, i.e., each pixel is assigned to one of a set of labels. Features are learned from pixel intensity values with stacked convolutional autoencoders in an unsupervised manner. The features are used for the purpose of initial classification with a multilayer perceptron. Then a CRF model is introduced for modeling the local and contextual information jointly in order to improve the segmentation. For the purpose of decreasing the time complexity, we perform labeling at superpixel level. In the CRF model, graph nodes are represented by superpixels. The label of each pixel is determined by the label of the superpixel to which it belongs. Experiments on three public datasets demonstrate that, compared to previous methods, the proposed method achieves more accurate segmentation results and is much faster.},

abstract={Inkball models provide a tool for matching and comparison of spatially structured markings such as handwritten characters and words. Hidden Markov models offer a framework for decoding a stream of text in terms of the most likely sequence of causal states. Prior work with HMM has relied on observation of features that are correlated with underlying characters, without modeling them directly. This paper proposes to use the results of inkball-based character matching as a feature set input directly to the HMM. Experiments indicate that this technique outperforms other tested methods at handwritten word recognition on a common benchmark when applied without normalization or text deslanting.},

abstract={In this paper, we present an efficient page segmentation method for historical document images. Many existing methods either rely on hand-crafted features or perform rather slow as they treat the problem as a pixel-level assignment problem. In order to create a feasible method for real applications, we propose to use superpixels as basic units of segmentation, and features are learned directly from pixels. An image is first oversegmented into superpixels with the simple linear iterative clustering (SLIC) algorithm. Then, each superpixel is represented by the features of its central pixel. The features are learned from pixel intensity values with stacked convolutional autoencoders in an unsupervised manner. A support vector machine (SVM) classifier is used to classify superpixels into four classes: periphery, background, text block, and decoration. Finally, the segmentation results are refined by a connected component based smoothing procedure. Experiments on three public datasets demonstrate that compared to our previous method, the proposed method is much faster and achieves comparable segmentation results. Additionally, much fewer pixels are used for classifier training.},

abstract = "In this work we provide details on a new and effective approach able to generate Gaussian Mixture Models (GMMs) for the classification of aggregated time series. More specifically, our procedure can be applied to time series that are aggregated together by adding their features. The procedure takes advantage of the additive property of the Gaussians that complies with the additive property of the features. Our goal is to classify aggregated time series, i.e. we aim to identify the classes of the single time series contributing to the total. The standard approach consists in training the models using the combination of several time series coming from different classes. However, this has the drawback of being a very slow operation given the amount of data. The proposed approach, called GMMs aggregation procedure, addresses this problem. It consists of three steps: (i) modeling the independent classes, (ii) generation of the models for the class combinations and (iii) simplification of the generated models. We show the effectiveness of our approach by using time series in the context of electrical appliance consumption, where the time series are aggregated by adding the active and reactive power. Finally, we compare the proposed approach with the standard procedure.",

analysing the entire intronic sequences of the F8 gene in 15
haemophilia A patients by next generation sequencing. All
patients had a mild to moderate phenotype and no mutation in
the coding sequence and splice sites of the F8 gene could be
diagnosed so far. Next generation sequencing data revealed
23 deep intronic candidate variants in several F8 introns,
including six recurrent variants and three variants that
have been described before. One patient additionally showed
a deletion of 9.2 kb in intron 1, mediated by Alu-type
repeats. Several bioinformatic tools were used to score the
variants in comparison to known pathogenic F8 mutations in
order to predict their deleteriousness. Pedigree analyses
showed a correct segregation pattern for three of the
presumptive mutations. In each of the 15 patients analysed,
at least one deep intronic variant in the F8 gene was
identified and predicted to alter F8 mRNA splicing. Reduced
F8 mRNA levels and/or stability would be well compatible
with the patients' mild to moderate haemophilia A
phenotypes. The next generation sequencing approach used
proved an efficient method to screen the complete F8 gene

Abstract = {Purpose: To detect and quantify eye blinks during 24-hour intraocular pressure (IOP) monitoring with a contact lens sensor (CLS). Methods: A total of 249 recordings of 24-hour IOP patterns from 202 participants using a CLS were included. Software was developed to automatically detect eye blinks, and wake and sleep periods. The blink detection method was based on detection of CLS signal peaks greater than a threshold proportional to the signal amplitude. Three methods for automated detection of the sleep and wake periods were evaluated. These relied on blink detection and subsequent comparison of the local signal amplitude with a threshold proportional to the mean signal amplitude. These methods were compared to manual sleep/wake verification. In a pilot, simultaneous video recording of 10 subjects was performed to compare the software to observer-measured blink rates. Results: Mean (SD) age of participants was 57.4 $\pm$ 16.5 years (males, 49.5%). There was excellent agreement between software-detected number of blinks and visually measured blinks for both observers (intraclass correlation coefficient [ICC], 0.97 for observer 1; ICC, 0.98 for observer 2). The CLS measured a mean blink frequency of 29.8 $\pm$ 15.4 blinks/min, a blink duration of 0.26 $\pm$ 0.21 seconds and an interblink interval of 1.91 $\pm$ 2.03 seconds. The best method for identifying sleep periods had an accuracy of 95.2 $\pm$ 0.5%. Conclusions: Automated analysis of CLS 24-hour IOP recordings can accurately quantify eye blinks, and identify sleep and wake periods. Translational Relevance: This study sheds new light on the potential importance of eye blinks in glaucoma and may contribute to improved understanding of circadian IOP characteristics.},

abstract={Data aggregation has been widely applied as efficient techniques in order to reduce the data redundancy and the communication load in Wireless Sensor Networks (WSNs). However, for dynamic scenarios, structured protocols may incur high overhead in the construction and the maintenance of the static structure. Without the explicit downstream and upstream relationship of nodes, it is also difficult to obtain high aggregation efficiency by using structure-free protocols. In order to address these aspects, we propose a semi-structured protocol based on the multi-objective tree. The routing scheme can explore the optimal structure by using the Ant Colony Optimization (ACO). Moreover, by using the prediction model for the arriving packets based on the sliding window, the adaptive timing policy can reduce the transmission delay and enhance the aggregation probability. Therefore, the packet transmission converges from both spatial and temporal points of view for the data aggregation procedure. Finally, simulation results validate the feasibility and the high efficiency of the novel protocol when compared with other existing approaches.},

abstract = {Activity recognition and prediction in buildings can have multiple positive effects in buildings: improve elderly monitoring, detect intrusions, maximize energy savings and optimize occupant comfort. In this paper we apply human activity recognition by using data coming from a network of motion and door sensors distributed in a Smart Home environment. We use Hidden Markov Models (HMM) as the basis of a machine learning algorithm on data collected over an 8-month period from a single-occupant home available as part of the WSU CASAS Smart Home project. In the first implementation the HMM models 24 hours of activities and classifies them in 8 distinct activity categories with an accuracy rate of 84.6{\%}. To improve the identification rate and to help detect potential abnormalities related with the duration of an activity (i.e. when certain activities last too much), we implement minimum duration modeling where the algorithm is forced to remain in a certain state for a specific amount of time. Two subsequent implementations of the minimum duration HMM (mean-based length modeling and quantile length modeling) yield a further 2{\%} improvement of the identification rate. To predict the sequence of activities in the future, Artificial Neural Networks (ANN) are employed and identified activities clustered in 3 principal activity groups with an average accuracy rate of 71-77.5{\%}, depending on the forecasting window. To explore the energy savings potential, we apply thermal dynamic simulations on buildings in central European climate for a period of 65 days during the winter and we obtain energy savings for space heating of up to 17{\%} with 3-hour forecasting for two different types of buildings.},

Abstract = {The automatic identification of appliances through the analysis of their electricity consumption has several purposes in Smart Buildings including better understanding of the energy consumption, appliance maintenance and indirect observation of human activities. Electric signatures are typically acquired with IoT smart plugs integrated or added to wall sockets. We observe an increasing number of research teams working on this topic under the umbrella Intrusive Load Monitoring. This term is used as opposition to Non-Intrusive Load Monitoring that refers to the use of global smart meters. We first present the latest evolutions of the ACS-F database, a collections of signatures that we made available for the scientific community. The database contains different brands and/or models of appliances with up to 450 signatures. Two evaluation protocols are provided with the database to benchmark systems able to recognise appliances from their electric signature. We present in this paper two additional evaluation protocols intended to measure the impact of the analysis window length. Finally, we present our current best results using machine learning approaches on the 4 evaluation protocols.},

Abstract = {In this paper we assess about the recognition of User Interaction events when handling electrical devices. This work is placed in the context of Intrusive Load Monitoring used for appliance recognition. ILM implies several Smart Metering Sensors to be placed inside the environment under analysis (in our case we have one Smart Metering Sensor per device). Our existing system is able to recognise the appliance class (as coffee machine, printer, etc.) and the sequence of states (typically Active / Non-Active) by using Hidden Markov Models as machine learning algorithm. In this paper we add a new layer to our system architecture called User Interaction Layer, aimed to infer the moments (called User Interaction events) during which the user interacts with the appliance. This layer uses as input the information coming from HMM (i.e. the recognised appliance class and the sequence of states). The User Interaction events are derived from the analysis of the transitions in the sequences of states and a ruled-based system adds or removes these events depending on the recognised class. Finally we compare the list of events with the ground truth and we obtain three different accuracy rates: (i) 96.3% when the correct model and the real sequence of states are known a priori, (ii) 82.5% when only the correct model is known and (iii) 80.5% with no a priori information.},

year={2015},
pages={861-865},
abstract={In this paper, we propose a method to recognize Sudoku puzzles containing both handwritten and printed digits from images taken with a mobile camera. The grid and the digits are detected using various image processing techniques including Hough Transform and Contour Detection. A Convolutional Deep Belief Network is then used to extract high-level features from raw pixels. The features are finally classified using a Support Vector Machine. One of the scientific question addressed here is about the capability of the Deep Belief Network to learn extracting features on mixed inputs, printed and handwritten. The system is thoroughly tested on a set of 200 Sudoku images captured with smartphone cameras under varying conditions, e.g. distortion and shadows. The system shows promising results with 92% of the cells correctly classified. When cell detection errors are not taken into account, the cell recognition accuracy increases to 97.7%. Interestingly, the Deep Belief Network is able to handle the complex conditions often present on images taken with phone cameras and the complexity of mixed printed and handwritten digits.},

Abstract = {Building Ultrascale computer systems is a hard problem, not yet solved and fully explored. Combining the computing resources of multiple organizations, often in different administrative domains with heterogeneous hardware and diverse demands on the system, requires new tools and frameworks to be put in place. During previous work we developed POP-Java, a Java programming language extension that allows to easily develop distributed applications in a heterogeneous environment. We now present an extension to the POP-Java language, that allows to create application centered networks in which any member can benefit from the computing power and storage capacity of its members. An accounting system is integrated, allowing the different members of the network to bill the usage of their resources to the other members, if so desired. The system is expanded through a similar process as seen in social networks, making it possible to use the resources of friend and friends of friends. Parts of the proposed system has been implemented as a prototype inside the POP-Java programming language.},

Abstract = {Ultrascale computing and bioinformatics are two rapidly growing fields with a big impact right now and even more so in the future. The introduction of next generation sequencing pushes current bioinformatics tools and workflows to their limits in terms of performance. This forces the tools to become increasingly performant to keep up with the growing speed at which sequencing data is created. Ultrascale computing can greatly benefit bioinformatics in the challenges it faces today, especially in terms of scalability, data management and reliability. But before this is possible, the algorithms and software used in the field of bioinformatics need to be prepared to be used in a heterogeneous distributed environment. For this paper we choose to look at sequence alignment, which has been an active topic of research to speed up next generation sequence analysis, as it is ideally suited for parallel processing. We present a multilevel stream based parallel architecture to transparently distribute sequence alignment over multiple cores of the same machine, multiple machines and cloud resources. The same concepts are used to achieve multithreaded and distributed parallelism, making the architecture simple to extend and adapt to new situations. A prototype of the architecture has been implemented using an existing commercial sequence aligner. We demonstrate the flexibility of the implementation by running it on different configurations, combining local and cloud computing resources.},

Abstract = {Over recent years next generation sequencing (NGS) technologies evolved from costly tools used by very few, to a much more accessible and economically viable technology. Through this recently gained popularity, its use-cases expanded from research environments into clinical settings. But the technical know-how and infrastructure required to analyze the data remain an obstacle for a wider adoption of this technology, especially in smaller laboratories. We present GensearchNGS, a commercial DNAseq software suite distributed by Phenosystems SA. The focus of GensearchNGS is the optimal usage of already existing infrastructure, while keeping its use simple. This is achieved through the integration of existing tools in a comprehensive software environment, as well as custom algorithms developed with the restrictions of limited infrastructures in mind. This includes the possibility to connect multiple computers to speed up computing intensive parts of the analysis such as sequence alignments. We present a typical DNAseq workflow for NGS data analysis and the approach GensearchNGS takes to implement it. The presented workflow goes from raw data quality control to the final variant report. This includes features such as gene panels and the integration of online databases, like Ensembl for annotations or Cafe Variome for variant sharing.},

Abstract = {NGS data analysis is increasingly popular in the diagnostics field thanks to advances in sequencing technologies which improved the speed, quantity and quality of the produced data. Due to those improvements, the analysis of the data requires an increasing amount of technical knowledge and processing power. Several software tools exist to handle these technical challenges involved in NGS data analysis. We present the latest improvements in one of those software-tools, GensearchNGS 1.6, a NGS data analysis software allowing users to go from raw NGS data to variant reports. We focus on the improvements made in terms of variant calling, annotation and filtering. The variant calling algorithm has been completely rewritten, based on the variant calling model used in Varscan 2, greatly improving its speed (over 10 times faster than Varscan 2, over 5 times faster than GATK) and accuracy, while reducing memory requirements. For the subsequent annotation of the called variants, various new datasources have been integrated, such as Human Phenotype Ontology and the clinical predictions from Ensembl, which give the user more information about the clinical relevance of the called variants. An initial prototype of the integration of interactome data from different sources, such as CCSB or BioGRID, is also presented, further increasing the available information for variant effect prediction. The addition of annotation data has been accompanied by various optimizations, keeping memory requirements and analysis times stable. The interactive variant filtering, which updates a variant list presented to the user while he changes the filters, has been further optimized, making it possible to filter variants interactively even on computers with limited processing power and memory. Similar improvements have also been made to the visualizer, allowing for a faster visualization requiring fewer resources, while integrating more data, such as the previously mentioned databases.},

We previously presented a way for GensearchNGS users to distribute sequence alignment over multiple computers. This possibility has now been expanded to combine multiple computers in the same network with cloud computing resources. For our prototype, the user can by request add Amazon AWS EC2 cloud instances to the alignment process. The cloud resources are dynamically created and destroyed on demand, transparently to the user. It is also possible to combine local alignment on the computer starting the alignment, distributed alignment on multiple computers in the same network and cloud computing in any possible configuration. Even completely offloading the alignment is now possible. This flexibility allows especially smaller laboratories to adapt the software configuration to their needs.},

@article{Wolf:2174,
Abstract = {Following the speed increases in next generation sequencing over recent years, the proportion of time spent in sequence analysis compared to sequencing has increasingly shifted towards sequence analysis. While certain analysis steps such as sequence alignment were able to benefit from various speed increases, others, equally important steps like variant calling or coverage analysis, did not receive the same improvements. Analysing NGS data remains a complicated and time consuming process, requiring a substantial amount of computing power. Most current approaches to address the increasing data quantity rely on the usage of more powerful hardware or offload calculations to the cloud. In this poster we show that by using modern software development techniques such as stream processing, those additional analysis steps can be sped up without changing the analysis results. Developing more efficient implementations of existing algorithms makes it possible to process larger datasets on existing infrastructure, without changing the analysis results. This not only reduces the overall cost of data analysis, but also gives researches more flexibility when exploring different settings for the data analysis. We present the application GNATY, a stand-alone version of NGS data analysis tools used in GensearchNGS [WKDD15] developed by Phenosystems SA. The goal during the development of the GNATY tools was not to create new methods with different results to existing approaches, but explore the possibilities of improving the efficiency of existing approaches. A modular architecture has been developed to create efficient sequence alignment analysis tools, using stream processing techniques which allow for multithreading and reusable data analysis blocks. The modular architecture uses a stream processing based workflow, efficiently splitting data access and data processing analysis steps, resulting in a more efficient use of the available computing resources. The architecture has been verified by implementing a variant caller based on the Varscan 2 [KZL+12] variant calling model, achieving a speedup of nearly 18 times. The results of the variant calling in GNATY are identical to Varscan 2, avoiding the issue of adding yet another variant calling model to the existing ones. To further demonstrate the flexibility and efficiency of the approach, the algorithm is also applied to coverage analysis. Compared to BEDtools 2 [QH10], GNATY was twice as fast to perform coverage analysis, while producing the exact same results. Through the example of 2 existing next generation sequencing data analysis algorithms which are reimplemented with an efficient stream based modular architecture, we show the performance potential in existing data analysis tools. We hope that our work will lead to more efficient algorithms in bioinformatics in general, lessening the hardware requirements to cope with the ever increasing amounts of data to be analysed. The developed GNATY software is freely available for non-commercial usage at http://gnaty.phenosystems.com/.},

Abstract = {We are motivated by the issue of classifying diseases of chronically ill patients to assist physicians in their everyday work. Our goal is to provide a performance comparison of state-of-the-art multi-label learning algorithms for the analysis of multivariate sequential clinical data from medical records of patients affected by chronic diseases. As a matter of fact, the multi-label learning approach appears to be a good candidate for modeling overlapped medical conditions, specific to chronically ill patients. With the availability of such comparison study, the evaluation of new algorithms should be enhanced. According to the method, we choose a summary statistics approach for the processing of the sequential clinical data, so that the extracted features maintain an interpretable link to their corresponding medical records. The publicly available MIMIC-II dataset, which contains more than 19,000 patients with chronic diseases, is used in this study. For the comparison we selected the following multi-label algorithms: ML-kNN, AdaBoostMH, binary relevance, classifier chains, \{HOMER\} and RAkEL. Regarding the results, binary relevance approaches, despite their elementary design and their independence assumption concerning the chronic illnesses, perform optimally in most scenarios, in particular for the detection of relevant diseases. In addition, binary relevance approaches scale up to large dataset and are easy to learn. However, the \{RAkEL\} algorithm, despite its scalability problems when it is confronted to large dataset, performs well in the scenario which consists of the ranking of the labels according to the dominant disease of the patient. },

Abstract = {Optimizationffices, factories and even private housings are more and more endowed with building management systems (BMS) targeting an increase of comfort as well as lowering energy costs. This expansion is made possible by the progress realized in pervasive computing, providing small sized and affordable sensing devices. However, current BMS are often based on proprietary technologies, making their interoperability and evolution more didcult. For example, we observe the emergence of new applications based on intelligent data analysis able to compute more complex models about the use of the building. Such applications rely on heterogeneous sets of sensors, web data, user feedback and self-learning algorithms. In this position paper, we discuss the role of Web technologies for standardizing the application layer, and thus providing a framework for developing advanced building applications. We present our vision of TASSo, a layered Web model facing actual and future challenges for building management systems.},

Due to their intrinsic properties and representation formats, they form small islands isolated from each other. In order to increase interoperability and release their full capabilities, we propose to represent devices descriptions including data and service invocation with a common model allowing to compose mashups of heterogeneous sensors. Pushing this paradigm further, we also propose to augment service descriptions with a discovery protocol easing automatic assimilation of knowledge. In this work, we describe the architecture supporting what can be called a Semantic Sensor Web-of-Things. As proof of concept, we apply our proposal to the domain of smart buildings, composing a novel ontology covering heterogeneous sensing, actuation and service invocation.

Abstract = {Data storage has become a major topic in sensor networks as large quantities of data need to be archived for future processing. In this paper, we present a cloud storage solution beneting from the available memory on smart things becoming data nodes. In-network storage reduces the heavy traffic resulting of the transmission of all the data to an outside central sink. The system built on agents allows an autonomous management of the cloud and therefore requires no human in the loop. It also makes an intensive use of Web technologies to follow the clear trend of sensors adopting the Web-of-Things paradigm. Further, we make a performance evaluation demonstrating its suitability in building management systems.},

Abstract = {Internet-of-Things (IoT) devices, especially sensors are producing large quantities of data that can be used for gathering knowledge. In this field, machine learning technologies are increasingly used to build versatile data-driven models. In this paper, we present a novel architecture able to execute machine learning algorithms within the sensor network, presenting advantages in terms of privacy and data transfer efficiency. We first argument that some classes of machine learning algorithms are compatible with this approach, namely based on the use of generative models that allow a distribution of the computation on a setof nodes. We then detail our architecture proposal, leveraging on the use of Web-of-Things technologies to ease integration into networks. The convergence of machine learning generative models and Web-of-Things paradigms leads us to the concept of virtual things exposing higher level knowledge by exploiting sensor data in the network. Finally, we demonstrate with a real scenario the feasibility and performances of our proposal.},

abstract = "Nowadays, pervasive application scenarios relying on sensor networks are gaining momentum. The field of smart buildings is a promising playground where the use of sensors allows a reduction of the overall energy consumption. Most of current applications are using the classical DNS which is not suited for the Internet-of-Things because of requiring humans to get it working. From another perspective, Web technologies are pushing in sensor networks following the Web-of-Things paradigm advocating to use RESTful APIs for manipulating resources representing device capabilities. Being aware of these two observations, we propose to build on top of Web technologies leading to a novel naming system that is entirely autonomous. In this work, we describe the architecture supporting what can be called an autonomous Web-oriented naming system. As proof of concept, we simulate a rather large building and compare the behaviour of our approach to the legacy DNS and Multicast DNS (mDNS).",

Abstract = {The emerging concept of Smart Building relies on an intensive use of sensors and actuators and therefore appears, at first glance, to be a domain of predilection for the IoT. However, technology providers of building automation systems have been functioning, for a long time, with dedicated networks, communication protocols and APIs. Eventually, a mix of different technologies can even be present in a given building. IoT principles are now appearing in buildings as a way to simplify and standardise application development. Nevertheless, many issues remain due to this heterogeneity between existing installations and native IP devices that induces complexity and maintenance efforts of building management systems. A key success factor for the IoT adoption in Smart Buildings is to provide a loosely-coupled Web protocol stack allowing interoperation between all devices present in a building. We review in this chapter different strategies that are going in this direction. More specifically, we emphasise on several aspects issued from pervasive and ubiquitous computing like service discovery. Finally, making the assumption of seamless access to sensor data through IoT paradigms, we provide an overview of some of the most exciting enabling applications that rely on intelligent data analysis and machine learning for energy saving in buildings.},

abstract = "Objective.
This research is motivated by the issue of classifying illnesses of chronically ill patients for decision support in clinical settings. Our main objective is to propose multi-label classification of multivariate time series contained in medical records of chronically ill patients, by means of quantization methods, such as bag of words (BoW), and multi-label classification algorithms. Our second objective is to compare supervised dimensionality reduction techniques to state-of-the-art multi-label classification algorithms. The hypothesis is that kernel methods and locality preserving projections make such algorithms good candidates to study multi-label medical time series.
Methods.
We combine BoW and supervised dimensionality reduction algorithms to perform multi-label classification on health records of chronically ill patients. The considered algorithms are compared with state-of-the-art multi-label classifiers in two real world datasets. Portavita dataset contains 525 diabetes type 2 (DT2) patients, with co-morbidities of DT2 such as hypertension, dyslipidemia, and microvascular or macrovascular issues. MIMIC II dataset contains 2635 patients affected by thyroid disease, diabetes mellitus, lipoid metabolism disease, fluid electrolyte disease, hypertensive disease, thrombosis, hypotension, chronic obstructive pulmonary disease (COPD), liver disease and kidney disease. The algorithms are evaluated using multi-label evaluation metrics such as hamming loss, one error, coverage, ranking loss, and average precision.
Results.
Non-linear dimensionality reduction approaches behave well on medical time series quantized using the BoW algorithm, with results comparable to state-of-the-art multi-label classification algorithms. Chaining the projected features has a positive impact on the performance of the algorithm with respect to pure binary relevance approaches.
Conclusions.
The evaluation highlights the feasibility of representing medical health records using the BoW for multi-label classification tasks. The study also highlights that dimensionality reduction algorithms based on kernel methods, locality preserving projections or both are good candidates to deal with multi-label classification tasks in medical time series with many missing values and high label density.",

Abstract = {In this paper we present a novel text line segmentation method for historical manuscript images. We use a pyramidal approach where at the first level, pixels are classified into: text, background, decoration, and out of page; at the second level, text regions are split into text line and non text line. Color and texture features based on Local Binary Patterns and Gabor Dominant Orientation are used for classification. By applying a modified Fast Correlation-Based Filter feature selection algorithm, redundant and irrelevant features are removed. Finally, the text line segmentation results are refined by a smoothing post-processing procedure. Unlike other projection profile or connected components methods, the proposed algorithm does not use any script-specific knowledge and is applicable to color images. The proposed algorithm is evaluated on three historical manuscript image datasets of diverse nature and achieved an average precision of 91% and recall of 84%. Experiments also show that the proposed algorithm is robust with respect to changes of the writing style, page layout, and noise on the image.},

The evaluation is performed on the Fribourg Product Image Database (FPID) that contains more than 3'000 pictures of consumer products taken using mobile phone cameras in realistic conditions. Using the evaluation protocol proposed with FPID, we explore the performance of different prepro- cessing and feature extraction. We observe that by using SURF, we can improve significantly the performance on this task. Image resizing and Lucene indexing are used in order to speed up CBIR task with SURF. We also show the benefit of using simple preprocessing of the images such as a proportional cropping of the images.

Abstract = {In this paper we present a physical structure detection method for historical handwritten document images. We considered layout analysis as a pixel labeling problem. By classifying each pixel as either periphery, background, text block, or decoration, we achieve high quality segmentation without any assumption of specific topologies and shapes. Various color and texture features such as color variance, smoothness, Laplacian, Local Binary Patterns, and Gabor Dominant Orientation Histogram are used for classification. Some of these features have so far not got many attentions for document image layout analysis. By applying an Improved Fast Correlation-Based Filter feature selection algorithm, the redundant and irrelevant features are removed. Finally, the segmentation results are refined by a smoothing post-processing procedure. The proposed method is demonstrated by experiments conducted on three different historical handwritten document image datasets. Experiments show the benefit of combining various color and texture features for classification. The results also show the advantage of using a feature selection method to choose optimal feature subset. By applying the proposed method we achieve superior accuracy compared with earlier work on several datasets, e.g., We achieved 93% accuracy compared with 91% of the previous method on the Parzival dataset which contains about 100 million pixels.},

abstract={Most of hierarchical fault tolerance strategies did not pay much attention to scalability of fault tolerance. In distributed system, scalability is a very important feature. To tolerant failures when the scale of the system changing is a normal and important scenario. Especially in nowadays, almost all the cloud computing companies provide their computing services elastically. To add extra devices or remove devices in order to provide different services happens all the time. In such a scenario, it is very important that the fault tolerance strategy is scalable. In this paper, we introduce dynamic programming thoughts to build hierarchical regions as communities for fault tolerance strategy and apply different strategies based on communities instead of a single process. We call this fault tolerance strategy as Community Fault Tolerance. It cannot only reduce the memory overload by eliminating the number of records of messages inside the community region, but also provides a good characteristic of scalability. The scalability property of our strategy makes it handle with the scenario of adding devices or removing devices in the distributed system easily.},

year={2014},
pages={418-421},
abstract={In LTE-A cellular networks there is a fundamental trade-off between the cell throughput and fairness levels for preselected users which are sharing the same amount of resources at one transmission time interval (TTI). The static parameterization of the Generalized Proportional Fair (GPF) scheduling rule is not able to maintain a satisfactory level of fairness at each TTI when a very dynamic radio environment is considered. The novelty of the current paper aims to find the optimal policy of GPF parameters in order to respect the fairness criterion. From sustainability reasons, the multi-layer perceptron neural network (MLPNN) is used to map at each TTI the continuous and multidimensional scheduler state into a desired GPF parameter. The MLPNN non-linear function is trained TTI-by-TTI based on the interaction between LTE scheduler and the proposed intelligent controller. The interaction is modeled by using the reinforcement learning (RL) principle in which the LTE scheduler behavior is modeled based on the Markov Decision Process (MDP) property. The continuous actor-critic learning automata (CACLA) RL algorithm is proposed to select at each TTI the continuous and optimal GPF parameter for a given MDP problem. The results indicate that CACLA enhances the convergence speed to the optimal fairness condition when compared with other existing methods by minimizing in the same time the number of TTIs when the scheduler is declared unfair.},

Abstract = {Diagnosing the glaucoma is a very difficult task for healthcare professionals. High intraocular pressure (IOP) remains the main treatable symptom of this degenerative disease which leads to blindness. Nowadays, new types of wearable sensors, such as the contact lens sensor Triggerfish{\textregistered}, provide an automated recording of 24-hour profile of ocular dimensional changes related to IOP. Through several clinical studies, more and more IOP-related profiles have been recorded by those sensors and made available for elaborating data-driven experiments. The objective of such experiments is to analyse and detect IOP pattern differences between ill and healthy subjects. The potential is to provide medical doctors with analysis and detection tools allowing them to better diagnose and treat glaucoma. In this paper we present the methodologies, signal processing and machine learning algorithms elaborated in the task of automated detection of glaucomatous IOP- related profiles within a set of 100 24-hour recordings. As first convincing results, we obtained a classification ROC AUC of 81.5%.},

The scenario of use is appliance identification with emerging applications such as domestic electricity consumption understanding, load shedding management and indirect human activity monitoring. The novelty of our work is to use low-end electricity consumption sensors typically located at the plug. Our approach consists in acquiring signatures at a low frequency, which contrast with high frequency transient analysis approaches that are costlier and have been well studied in former research works. Electrical consumption signatures comprise real power, reactive power, RMS current, RMS voltage, frequency and phase of voltage relative to current. A total of 225 appliances were recorded over two sessions of one hour. The database is balanced with 15 different brands/models spread into 15 categories. Two realistic appliance recognition protocols are proposed and the database is made freely available to the scientific community for the experiment reproducibility. We also report on recognition results following these protocols and using baseline recognition algorithms like k-NN and GMM.},

We apply Hidden Markov Models to appliance signatures for the identification of their category and of the most probable sequence of states. The electrical signatures are measured at low frequency (101 Hz) and are sourced from a specific database. We follow two predefined protocols for providing comparable results. Recovering information on the actual appliance state permits to potentially adopt energy saving measures, as switching off stand-by appliances or, generally speaking, changing their state. Moreover, in most of the cases appliance states are related to user activities: the user interaction usually involves a transition of the appliance state. Information about the state transition could be useful in Smart Home / Building Systems to reduce energy consumption and increase human comfort. We report the results of the classification tasks in terms of confusion matrices and accuracy rates. Finally, we present our application for a real-time data visualization and the recognition of the appliance category with its actual state.},

Abstract = {The automatic recognition of appliances through the monitoring of their electricity consumption finds many applications in smart buildings. In this paper we discuss the use of Hidden Markov Models (HMMs) for appliance recognition using so-called intrusive load monitoring (ILM) devices. Our motivation is found in the observation of electric signatures of appliances that usually show time varying profiles depending to the use made of the appliance or to the intrinsic internal operating of the appliance. To determine the benefit of such modelling, we propose a comparison of stateless modelling based on Gaussian mixture models and state-based models using Hidden Markov Models. The comparison is run on the publicly available database ACS-F1. We also compare differ- ent approaches to determine the best model topologies. More specifically we compare the use of a priori information on the device, a procedure based on a criteria of log-likelihood maximization and a heuristic approach.},

Abstract = {In this paper, we propose a method to detect and recognize a Sudoku puzzle on images taken from a mobile camera. The lines of the grid are detected with a Hough transform. The grid is then recomposed from the lines. The digits position are extracted from the grid and finally, each character is recognized using a Deep Belief Network (DBN). To test our implementation, we collected and made public a dataset of Sudoku images coming from cell phones. Our method proved successful on our dataset, achieving 87.5% of correct detection on the testing set. Only 0.37% of the cells were incorrectly guessed. The algorithm is capable of handling some alterations of the images, often present on phone-based images, such as distortion, perspective, shadows, illumination gradients or scaling. On average, our solution is able to produce a result from a Sudoku in less than 100ms.},

The tool and its algorithms are dedicated to artificial Arabic text embedded in video news in the form of static text as well as scrolling one. It is performed at two different levels. Including specificities of Arabic script, the tool manages a global level which concerns the entire video and a local level which concerns any specific frame extracted from the video. The global annotation is performed manually thanks to a user interface. As a result of this step, we obtain the global xml file. The local annotation at the frame level is done automatically according to the information contained in the global metafile and a proposed text tracking algorithm. The main application of our tool is the ground truthing of textual information in video content. It is being used for this purpose in the Arabic Text in Video (AcTiV) database project in our lab. One of the functions that AcTiV provides, is a benchmark to compare existing and future Arabic video OCR systems.},

abstract = "Smart buildings tend to democratize both in new and renovated constructions aiming at minimizing energy consumption and maximizing comfort. They rely on dedicated networks of sensors and actuators orchestrated by management systems. Those systems tend to migrate from simple reactive control to complex predictive systems using self- learning algorithms requiring access to history data. The underlying building networks are often heterogeneous, leading to complex software systems having to implement all the available protocols and resulting in low system integration and heavy maintenance efforts. Typical building networks offer no common standardized application layer for building applications. This is not only true for data access but also for functionality discovery. They base on specific protocols for each technology, that are requiring expert knowledge when building software applications on top of them. The emerging Web-of-Things (WoT) framework, using well-known technologies like HTTP and RESTful APIs to offer a simple and homogeneous application layer must be considered as a strong candidate for standardization purposes. In this work, we defend the position that the WoT framework is an excellent candidate to elaborate next generation BMS systems, mainly due to the simplicity and universality of the telecommunication and application protocols. Further to this, we investigate the possibility to implement a gateway allowing access to devices connected to KNX and EnOcean networks in a Web-of-Things manner. By taking advantage of the bests practices of the WoT, we show the possibility of a fast integration of KNX in every control system. The elaboration of WoT gateways for EnOcean network presents further challenges that are described in the paper, essentially due to optimization of the underlying communication protocol.",

The WoT offers new ways to build mashups of object services, notably in smart buildings composed of sensors and actuators. Many things are now taking advantage of the progresses of embedded systems relying on the ubiquity of Wi-Fi networks following the 802.11 standards. Such things are often battery powered and the question of energy efficiency is therefore critical. In our research, we believe that several optimizations can be applied in the application layer to optimize the energy consumption of things. More specifically in this paper, we propose an hybrid layer automatically selecting the most appropriate communication protocol between current standards of WoT. Our results show that indeed not all protocols are equivalent in terms of energy consumption, and that some noticeable energy saves can be achieved by using our hybrid layer. ",

abstract = "We aim at the elaboration of Information Systems able to optimize energy consumption in buildings while preserving human comfort. Our focus is in the use of state-based stochas- tic modeling applied to temporal signals acquired from heterogeneous sources such as distributed sensors, weather web services, calendar information and user triggered events. Our general scientific objectives are: (1) global instead of local optimization of building automation sub-systems (heating, ventilation, cooling, solar shadings, electric lightings), (2) generalization to unseen building configuration or usage through self-learning data- driven algorithms and (3) inclusion of stochastic state-based modeling to better cope with seasonal and building activity patterns. We leverage on state-based models such as Hidden Markov Models (HMMs) to be able to capture the spatial (states) and temporal (sequence of states) characteristics of the signals. We envision several application layers as per the intrinsic nature of the signals to be modeled. We also envision room-level systems able to leverage on a set of distributed sensors (temperature, presence, electricity consumption, etc.). A typical example of room-level system is to infer room occupancy information or activities done in the rooms as a function of time. Finally, building-level systems can be composed to infer global usage and to propose optimization strategies for the building as a whole. In our approach, each layer may be fed by the output of the previous layers.
More specifically in this paper, we report on the design, conception and validation of several machine learning applications. We present three different applications of state-based modeling. In the first case we report on the identification of consumer appliances through an analysis of their electric loads. In the second case we perform the activity recognition task, representing human activities through state-based models. The third case concerns the season prediction using building data, building characteristic parameters and meteorological data.",

The literature has proved the difficulty for Arabic text recognition systems to treat multi-font and multi-size word images. This is due to the variability induced by some font family, in addition to the inherent difficulties of Arabic writing including cursive representation, overlaps and ligatures. This research work proposes an efficient stochastic approach to tackle the problem of font and size recognition. Our method treats a word image with a fixed-length, overlapping sliding window. Each window is represented with a 102 features whose distribution is captured by Gaussian Mixture Models (GMMs). We present three systems: (1) a font recognition system, (2) a size recognition system and (3) a font and size recognition system. We demonstrate the importance of font identification before recognizing the word images with two multi-font Arabic OCRs (cascading and global). The cascading system is about 23% better than the global multi-font system in terms of word recognition rate on the Arabic Printed Text Image (APTI) database which is freely available to the scientific community.",

Investigating their unique architecture allows to capture insights and to understand the function and evolution of these complex systems. Ecological networks such as food-webs and niche-overlap graphs are considered as complex systems. The main purpose of this work is to compare the topology of 15 real niche-overlap graphs with random ones. Five measures are treated in this study: (1) the clustering coefficient, (2) the between ness centrality, (3) the assortativity coefficient, (4) the modularity and (5) the number of chord less cycles. Significant differences between real and random networks are observed. Firstly, we show that niche-overlap graphs display a higher clustering and a higher modularity compared to random networks. Moreover we find that random networks have barely nodes that belong to a unique sub graph (i.e. between ness centrality equal to 0) and highlight the presence of a small number of chord less cycles compared to real networks. These analyses may provide new insights in the structure of these real niche-overlap graphs and may give important implications on the functional organization of species competing for some resources and on the dynamics of these systems.",

However, in some contexts such as smart buildings where the objective is to control the equipments to save energy, the underlying WoT framework including hardware, communication and APIs must itself be energy efficient.

This database is a large-scale benchmarking of open-vocabulary, multi-font, multi-size and multi-style word recognition systems in Arabic. Such systems take as input a text image and compute as output a character string corresponding to the text included in the image. The challenges that are addressed by the database are in the variability of the sizes, fonts and styles used to generate the images. A focus is also given on low resolution images where anti-aliasing is generating noise on the characters being recognized. The database contains 45,313,600 single word images totalling more than 250 million characters. Ground truth annotation is provided for each image from an XML file. The annotation includes the number of characters, the number of pieces of Arabic words (PAWs), the sequence of characters, the size, the style, the font used to generate each image, etc. Secondly, we describe the Arabic Recognition Competition: Multi-Font Multi-Size Digitally Represented Text held in the context of the 11th International Conference on Document Analysis and Recognition (ICDAR’2011), during September 18–21, 2011, Beijing, China. This first edition of the competition used the freely available APTI database. Two groups with three systems participated in the competition. The systems were compared using the recognition rates at the character and word levels. The systems were tested on one test dataset which is unknown to all participants (set 6 of APTI database).

Abstract = {The existing resource and topology heterogeneity has
divided the scheduling solutions into local schedulers and
high-level schedulers (a.k.a. meta-schedulers). Although
much work has been proposed to optimise job queue based
scheduling, seldom has attention been put on the job sharing
behaviours between decentralised distributed resource pools,
which in turn raises a notable opportunity to exploit and
optimise the process of job sharing between reachable grid
dynamically and proactively. In our work, we introduce a
novel scheduling protocol named the community-aware
scheduling protocol (CASP), which dedicates to disseminate
scheduling events of each participating node to as many
remote nodes as possible. By means of the proposed protocol,
the scheduling process of each received job consists of two
phases with awareness of grid volatility. The implemented
prototype and evaluated results have shown the introduced
CASP is able to cooperate with a variety of local scheduling
algorithms as well as diverse types of grids.},

It comprises more than 600 individuals acquired simultaneously in three scenarios: i) over the Internet, ii) in an office environment with desktop PC, and iii) in indoor/outdoor environments with mobile portable hardware. Data has been acquired over two acquisition sessions and using different sensors in certain modalities. The three scenarios include a common part of audio and video data (face still images and talking face videos). Also, signature and fingerprint data has been acquired both with desktop PC and mobile portable hardware. Additionally, hand and iris data was acquired in the second scenario using desktop PC. Acquisition has been conducted by 11 European institutions taking part in the BioSecure NoE. Additional features of the BioSecure Multimodal Database (BMDB) are: balanced gender and age distributions, multimodal realistic scenarios with simple and quick tasks per modality, cross-European diversity (language, face, etc.), availability of demographic data (age, gender, handedness, visual aids, manual worker and English proficiency) and compatibility with other multimodal databases. The novel acquisition conditions of the BMDB database allow to perform new challenging research and evaluation of either monomodal or multimodal biometric systems, as in the recent BioSecure Multimodal Evaluation Campaign. A description of this campaign including baseline results of individual modalities from the new database is also given. The database is expected to be available for research purposes through the BioSecure Association during 2008.",

Tools are thus required to manage collections of 3D objects in a similar way to the management of image collections including the possibility to search using text queries. The system we are presenting in this paper goes one step further allowing to search for 3D objects not only using text queries but also using very simple similarity metrics inferred from the 3D spatial description. The multimodal search is stepwise. First, the user searches for a set of relevant objects using a classical text–based query engine. Second, the user selects a subset of the returned objects to perform a new query in the database according to a relevance feedback method. The relevance is computed using different geometric criteria that can be activated or deactivated. External objects can also be submitted directly for a similarity query. The current visual features are very simple but are planned to be extended in the future.",

abstract = "We analyze in this paper the impact of sub-models choice for automatic Arabic printed text recognition based on Hidden Markov Models (HMM). In our approach, sub-models correspond to characters shapes assembled to compose words models. One of the peculiarities of Arabic writing is to present various character shapes according to their position in the word. With 28 basic characters, there are over 120 different shapes. Ideally, there should be one sub-model for each different shape. However, some shapes are less frequent than others and, as training databases are finite, the learning process leads to less reliable models for the infrequent shapes. We show in this paper that an optimal set of models has then to be found looking for the trade-off between having more models capturing the intricacies of shapes and grouping the models of similar shapes with other. We propose in this paper different sets of sub-models that have been evaluated using the Arabic Printed Text Image (APTI) Database freely available for the scientific community.",

In this paper, we present a comparative study be- tween two strategies for the recognition of multi-font Arabic text. The first strategy is to use a global recognition system working independently on all the fonts. The second strategy is to use a so-called cascade built from a font identification system followed by font-dependent systems. In order to reach a fair comparison, the feature extraction and the modeling algorithms based on HMMs are kept as similar as possible between both approaches. The evaluation is carried out on the large and publicly available APTI (Arabic Printed Text Image) database with 10 different fonts. The results are showing a clear advantage of performance for the cascading approach. However, the cascading system is more costly in terms of cpu and memory.",

First, we do not need to perform a priori segmentation into characters, which is a difficult task for arabic text. Second, we use versatile and powerful GMMs able to model finely distributions of features in large multi-dimensional input spaces. We report on the evaluation of our system on the APTI (Arabic Printed Text Image) database using 10 different fonts and 10 font sizes. Considering the variability of the different font shapes and the fact that our system is independent of the font size, the obtained results are convincing and compare well with competing systems.",

If channel mismatch is too big and when different categories of channels can be identified, one possibility is to build a separate language recognition system for each category and then to fuse them together. This article uses a system selector that takes, for each utterance, the scores of one of the channel-category dependent systems. This selection is guided by a channel detector. We analyze different ways to design such channel detectors: based on cepstral features or on the Factor Analysis channel variability term. The systems are evaluated in the context of NIST’s LRE 2009 and run at 1.65\% minCavg for a subset of 8 languages and at 3.85\% minCavg for the 23 language setup.",

abstract = "This paper confirms the huge benefits of Factor Analysis over Maximum A-Posteriori adaptation for language recognition (up to 87\% relative gain). We investigate ways to cope with the particularity of NIST’s LRE 2009, containing Conversational Telephone Speech (CTS) and phone bandwidth segments of radio broadcasts (Voice Of America, VOA). We analyze GMM systems using all data pooled together, eigensession matrices estimated on a per condition basis and systems using a concatenation of these matrices. Results are presented on all LRE 2009 test segments, as well as only on the CTS or only on the VOA test utterances. Since performances on all 23 languages are not trivial to compare, due to lacking language–channel combinations in the training and also in the testing data, all systems are also evaluated in the context of the subset of 8 common languages. Addressing the question if a fusion of two channel specific systems may be more beneficial than putting all data together, we study an oracle based system selector. On the 8 language subset, a pure CTS system performs at a minimal average cost of 2.7\% and pure VOA at 1.9\% minCavg on their respective test conditions. The fusion of these two systems runs at 2.0\% minCavg. As main observation, we see that the way we estimate the session compensation matrix has not a big influence, as long as the language–channel combinations cover those used for training the language models. Far more crucial is the kind of data used for model estimation.",

The main benefit of this methodology lies in the simultaneous acquisition of two sources of biometric information with a better accuracy at no extra cost in terms of time or inconvenience. Another benefit comes from an increased difficulty for forgers willing to perform imitation attacks as two signals need to be reproduced. Our first strategy was to model independently both streams of data and to perform a fusion at the score level using state-of-the-art modelling tools and training algorithms. We report here on a second strategy, complementing the first one and aiming at modelling both streams of data jointly. This approach uses a recognition system to compute the forced alignment of Hidden Markov Models (HMMs). The system then tries to determine synchronization patterns using these two alignments of handwriting and speech and computes a new score according to these patterns. In this paper, we present these authentication systems with the focus on the joint modelling. The evaluation is performed on MyIDea, a realistic multimodal biometric database. Results show that a combination of the different modelling strategies (independent and joint) can improve the system performance on spoken handwriting data.",

Data according to these two scenarios have been recorded from a set of 70 users. In the first part of the paper, we describe the acquisition procedure and we comment on the viability and usability of such simultaneous recordings. Our conclusions are supported by a short survey performed with the users. In the second part, we present the authentication systems that we have developed for both scenarios.

abstract = "Evaluating speaker verification algorithms on relevant speech corpora is a key issue for measuring the progress and discovering the remaining difficulties of speaker verification systems. A common evaluation framework is also a key point when comparing systems produced by different labs. The speech group of the National Institute of Standards and Technology (NIST) has been organizing evaluations of text-independent telephony speaker verification technologies since 1997, with an increasing success and number of participants over the years. These NIST evaluations have been recognized by the speaker verification scientific community as a key factor for the improvement of the algorithms over the last decade. However, these evaluations measure exclusively the effectiveness in term of performance of the systems, assuming some conditions of use that are sometimes far away from any real-life commercial context for telephony applications. Other important aspects of speaker verification systems are also ignored by such evaluations, such as the efficiency, the usability and the robustness of the systems against impostor attacks. In this paper we present a review of the current NIST speaker verification evaluation methods, trying to put objectively into evidence their current benefits and limitations. We also propose some concrete solutions for going beyond these limitations.",

abstract = "Speaking is the most natural mean of communication between humans. Driven by a great deal of potential applications in human-machine interaction, systems have been developed to automatically extract the different pieces of information conveyed in the speech signal. There are three major tasks. In speech recognition tasks, the automatic system aims at discovering the sequence of words forming the spoken message. In language recognition tasks, the system attempts to identify the language used in a given piece of speech signal. Finally, speaker recognition systems aim to discover information about the identity of the speaker. Speaker recognition finds applications in many different areas such as access control, transaction authentication, law enforcement, speech data management and personalization. As for other biometric technologies the prime motivation of speaker recognition is to achieve a more usable and reliable personal identification than by using artifacts such as keys, badges, magnetic cards or memorized passwords. Interestingly, speaker recognition is one of the few biometric approach which is not based on image processing. Speaker recognition systems are often said to be performance-based since the user has to produce a sequence of sound. This is also a major difference with other passive biometrics for which the cooperation of the authenticated person is not requested, such as for fingerprints, iris or face recognition systems. Speaker recognition technologies are often ranked as less accurate than other biometric technologies such as finger print or iris scan. However, there are two main factors that make voice a compelling biometric. First, there is a proliferation of automated telephony services for which speaker recognition can be directly applied. Telephone handsets are indeed available basically everywhere and provide the required sensors for the speech signal. Second, talking is a very natural gesture, often considered as lowly intrusive by users as no physical contact is requested. These two factors, added to the recent scientific progresses, made voice biometric converge into a mature technology. Commercial products offering voice biometric are now available from different vendors. However, many technical and non-technical issues, discussed later in this chapter, still remain open and need to be tackled.",

abstract = "We are proposing a new user authentication system based on spoken signatures where online signature and speech signals are acquired simultaneously. The main benefit of this multimodal approach is a better accuracy at no extra costs for the user in terms of access time or inconvenience. Another benefit lies in a better robustness against intentional forgeries due to the extra difficulty for the forger to produce both signals. We have set up an experimental framework to measure these benefits on MyIDea, a realistic multimodal biometric database publicly available. More specifically, we evaluate the performance of state-of-the-art modelling systems based on GMM and HMM applied independently to the pen and voice signal where a simple rule-based score fusion procedure is used. We conclude that the best performance is achieved by the HMMs, provided that their topology is optimized on a per user basis. Furthermore, we show that more precise models can be obtained through the use of Maximum a posteriori probability (MAP) training instead of the classically used Expectation Maximization (EM). We also measure the impact of multi-session scenarios versus mono-session scenarios and the impact of skilled versus unskilled signature forgeries attacks.",

abstract = "We present in this paper a new forgery scenario for the evaluation of face verification systems. The scenario is a replay-attack where we assume that the forger has got access to a still picture of the genuine user. The forger is then using a dedicated software to realistically animate the face image, reproducing head and lip movements according to a given speech waveform. The resulting forged video sequence is finally replayed to the sensor. Such attacks are nowadays quite easy to realize for potential forgers and can be opportunities to attempt to forge text-prompted challenge-response configurations of the verification system. We report the evaluation of such forgeries on the BioSecure BMEC talking face database where a set of 430 users are forged according to this face animation procedure. As expected, results show that these forgeries generate much more false acceptation in comparison to the classically used random forgeries. These results clearly show that such kind of forgery attack potentially represents a critical security breach for talking-face verification systems.",

The presented paper describes two preliminary studies about character identification at very low resolution (72 dpi) and small font sizes (3-12 pts). The proposed character identification system delivers identification rates up to 99.93 percents for 12'600 isolated character samples and up to 99.89 percents for 300'000 character samples in context.",

abstract = "Speaker verification finds applications in many different areas such as access control, transaction authentication, law enforcement, speech data management and personalization. As for other biometric technologies the prime motivation of speaker recognition is to achieve a more usable and reliable personal identification than by using artifacts such as keys, badges, magnetic cards or memorized passwords. Speaker verification technologies are often ranked as less accurate than other biometric technologies such as iris scan or fingerprints. However, there are two main factors that make voice a compelling biometric. First, there is a proliferation of automated telephony services for which speaker recognition can be directly applied. Second, talking is a very natural gesture, often considered as lowly intrusive by users as no physical contact is requested. These two factors, added to the recent scientific progresses, made voice biometric converge into a mature technology.",

In this scenario, we assume that the forger has got access to a static version of the genuine signature, is using a dedicated software to automatically recover dynamics of the signature and is using these regained signatures to break the verification system. We also show that automated procedures can be built to regain signature dynamics, making some simple assumptions on how signatures are performed. We finally report on the evaluation of these procedures on the MCYT-100 signature database on which regained versions of the signatures are generated. This set of regained signatures is used to evaluate the rejection performance of a baseline dynamic signature verification system. Results show that the regained forgeries generate much more false acceptation in comparison to the random and low-force forgeries available in the MCYT-100 database. These results clearly show that such kind of forgery attacks can potentially represent a critical security breach for signature verification systems.",

More specifically, we report in this paper on significant improvements of our initial system that was based on Gaussian Mixture Models (GMMs) applied independently to the pen and voice signal. We show that the GMMs can be advantageously replaced by Hidden Markov Models (HMMs) provided that the number of state used for the topology is optimized and provided that the model parameters are trained with a Maximum a Posteriori (MAP) adaptation procedure instead of the classically used Expectation Maximization (EM).

abstract = "Recognition of speaker identity based on modeling the streams produced by phonetic decoders (phonetic speaker recognition) has gained popularity during the past few years. Two of the major problems that arise when phone based systems are being developed are the possible mismatches between the development and evaluation data and the lack of transcribed databases. Data-driven segmentation techniques provide a potential solution to these problems because they do not use transcribed data and can easily be applied on development data minimizing the mismatches. In this paper we compare speaker recognition results using phonetic and data-driven decoders. To this end, we have compared the results obtained with a speaker recognition system based on data-driven acoustic units and phonetic speaker recognition systems trained on Spanish and English data. Results obtained on the NIST 2005 Speaker Recognition Evaluation data show that the data-driven approach outperforms the phonetic one and that further improvements can be achieved by combining both approaches.",

abstract = "This document describes the acquisition protocols of MyIDea, a new large and realistic multimodal biometric database designed to conduct research experiments in Identity Verification (IV). The key points of MyIDea are threefold: (1) it is strongly multimodal; (2) it implements realistic scenarios in an open-set framework; (3) it uses sensors of different quality to record most of the modalities. The combination of these three points makes MyIDea novel and pretty unique in comparison to existing databases. Furthermore, special care is put in the design of the acquisition procedures to allow MyIDea to complement existing databases such as BANCA, MCYT or BIOMET. MyIDea includes talking face, audio, fingerprints, signature, handwriting and hand geometry. MyIDea will be available early 2006 with an initial set of 104 subjects recorded over three sessions. Other recording sets will be potentially planned in 2006.",

The segmental approaches described in this paper are meant to exploit these differences for speaker verification purposes. For such approaches, the speech is divided into different classes, and the speaker modeling is done for each class. The speech segmentation applied is based on automatic language independent speech processing tools that provide a segmentation of the speech requiring neither phonetic nor orthographic transcriptions of the speech data. Two different speaker modeling approaches, based on multilayer perceptrons (MLPs) and on Gaussian mixture models (GMMs), are studied. The MLP-based segmental systems have performance comparable to that of the global MLP-based systems, and in the mismatched train-test conditions slightly better results are obtained with the segmental MLP system. The segmental GMM systems gave poorer results than the equivalent global GMM systems.",

abstract = "In this thesis, we are concerned with the two fields of automatic speech recognition (ASR) and automatic speaker recognition (ASkR) in telephony. More precisely, we are interested in systems based on hidden Markov models (HMMs) in which artificial neural networks (ANNs) are used in place of more classical tools. This work is dedicated to the analysis of three approaches. The first one, mainly original, concerns the use of Self-Organizing Maps in discrete HMMs for isolated word speech recognition. The second approach concerns continuous hybrid HMM/ANN systems, extensively studied in previous research work. The system is not original in its form but its analysis permitted to bring a new theoretical framework and to introduce some extensions regarding the way the system is trained. The last part concerns the implementation of a new ANN segmental approach for text-independent speaker verification.",

abstract = "Most of text-independent speaker verification techniques are based on modelling the global probability distribution function (pdf) of speakers in the acoustic vector space. Our paper presents an alternative to this approach with a class-dependent verification system using automatically determined segmental units. Segments are found with temporal decomposition and labelled through unsupervised clustering. The core of the system is based on a set of multi-layer perceptrons (MLP) trained to discriminate between client and an independent set of world speakers. Each MLP is dedicated to work with data segments that were previously selected as belonging to a particular class. The last step of the system is a recombination of MLP scores to take the verification decision. Issues and potential advantages of the segmental approach are presented. Performances of global and segmental approaches are reported on the NIST'98 data (250 female and 250 male speakers), showing promising results for the proposed new segmental approach. Comparison with state of the art system, based on Gaussian Mixture Modelling is also included.",

It is khown that, with similar experimental conditions, nasals, fricatives and vowels convey more speaker specific informations than plosives and liquids. Regarding the influence of the frame-to-frame temporal information, significant improvements are reported from the inclusion of several acoustic frames at the input of the MLPs. Results tend also to show that each phoneme has its optimal MLP context size giving the best Equal Error Rate (EER).",

It is shown that hybrid HMM/ANN systems, in which the ANN part estimates local posteriors, can be used to modelize global model posteriors. This formalization provides us with a clear theory in which both REMAP and ``classical'' Viterbi trained hybrid systems are unified. Second, a new forward-backward training of hybrid HMM/ANN systems is derived from the previous formulation. Comparisons of performance between Viterbi and forward-backward hybrid systems are presented and discussed.",

In its current version (January 96) and amongst other things, POST can perform simple feature extraction, training and testing of word and subword Hidden Markov Models (HMMs) with discrete and multigaussian statistical modelling. In this parer, the implementation of the parallelism is discussed and an evaluation of the performances on a telephone database is presented.

The purpose of this paper is to show that future prices do not have to be known to make successful investments and that anticipating movements (increases or decreases) of the price can be sufficient. Probabilistic classification systems based on pattern recognition theory appear to be a good way to reach this objective. Moreover, they include some other advantages, principally in terms of risk management. Results show satisfactory classification hit rates but a rather poor translation into financial gains.
