To the best of current knowledge, the performance of federated learning predominantly depends on the efficiency of the aggregation server scheme utilized to consolidate model parameters received from distributed local devices. However, in practical scenarios, the global server often faces single-point failures due to four major issues: 1) variations in data distribution settings, such as independent identical distribution (IID) or non-independent identical distribution; 2) communication overhead; 3) limitations in hardware and resource storage availability; and 4) diverse participant participation behaviors. To address the latter concern, limited research has endeavored to establish a correlation between these heterogeneous settings and federated learning performance by analyzing different aspects of participant behavior. Inspired by the absence of a definitive verdict regarding the relationship between the global server and participant behavior, this paper investigates the aspect of participant selection methods and conducts a detailed comparative study among various participant selection methods

The emergence of so many online social networks (OSNs), such as Twitter, YouTube...etc, has significantly altered the global landscape of human connections and interactions. OSNs have become an integral part of people’s lives and have led to an explosion in the volume and variety of information available for research and analysis. In social network analysis (SNA), Influential user identification in OSN involves detecting users who have a significant impact on information dissemination and network dynamics is a fundamental research task. It plays an important role in different domains such as political movements, health applications, innovation dissemination, news spreading, and viral marketing. In this paper, we introduce a theoretical framework for identifying influential users based on both structural and behavioral factors of online social networks. We first present the problem statement and provide a review of pertinent background knowledge. Subsequently, our proposed framework is explained and discussed.

Frequently item-sets mining, also known as FIM, is a data mining technique used to extract useful knowledge from datasets. FIM is plagued by a number of issues, including high storage charges, a huge time and memory consumption. Classical FIM algorithms suffer with the great number of generated itemsets which contains useless items. And presupposes that all itemsets have the same importance. To deal with these limitations, high-utility itemsets (HUI) is proposed, which are as subset of FIM with the consideration of Utility or profit measure. In the last decade, evolutionary approaches become a trend to solve HUIs mining problem (EA). This paper explores the use of evolutionary techniques in HUIs mining. Moreover, we present an evolutionary techniques-based HUIs mining classification including single objective, multi-objective and Hybrid optimization techniques. This article provides a comparative examination of methodologies and discusses theoretical features of a wide variety of algorithms that are inspired by nature.KeywordsHUIs miningBio-inspired algorithmsEvolutionary approaches

Social networks such as Facebook, Twitter, etc. have dramatically increased recently. These databases are massive and their use is time-consuming. In this work, we present an optimal calculation in graph mining for link prediction to reduce the runtime. For that purpose, we propose a novel approach that operates on the connected components of a network instead of the whole network. Thanks to this decomposition, we show that the results of all link prediction algorithms using local and path-based similarity measures can be achieved with much fewer computations and hence within a much shorter runtime. We show that this gain depends on the distribution of nodes in components and may be captured by the Gini and the variance measures. We propose a parallel architecture of the link prediction process based on the connected component's decomposition. To validate this architecture, we have carried out an experimental study on a wide range of well-known datasets. The obtained results clearly confirm the efficiency of exploiting the decomposition of the network into connected components in link prediction.

Given the still-existing restrictions of COVID-19, blended learning is undoubtedly becoming a better-fitting strategy for higher education institutions in underprivileged countries. Acknowledging the current changes in higher education, this study aims to investigate the elements that influence students’ satisfaction and their future preferences regarding blended learning in Algeria. A total of 782 questionnaires were collected from different Algerian universities. A structural Equation Modeling (SEM) analysis was conducted to investigate the relationship among the latent variables of the proposed theoretical model. Moreover, an unsupervised sentiment analysis approach was applied to analyze the qualitative data received as feedback from the participants. The results show that students perceived ease of use and perceived usefulness of blended learning had a significant positive impact on their satisfaction. Similarly, satisfaction had a positive influence on students’ future preferences regarding blended learning. In turn, students’ perceived ease of use and usefulness indirectly affected their future preferences, mediated by satisfaction. Additionally, qualitative data echoed students’ eagerness to adopt more advanced learning technologies and what obstacles currently stand in their way. The contribution of this study is to reflect the current situation of blended learning adoption in developing countries and to support future curriculum planning and development. It can also help teachers, students, and policymakers to make better decisions and recommendations for an improved and more sustainable learning and teaching environment in the future.

The conversation on the effectiveness of blended learning experience in Algerian higher education has not received the necessary attention compared to developed countries. Moreover, there is a scarcity of research that discusses the impact and benefits of the pandemic-induced changes in Algerian higher education. The primary goal of this paper is to initiate a deeper conversation about blended learning in Algerian Higher Education using an exploratory research method based on empirical evidence and quantitative data. It examines teachers’ and students’ satisfaction with blended teaching and learning at Algerian universities since the start of Covid-19. There was a total of 782 students and 82 teachers involved with valid questionnaire responses, from two different Algerian public universities. The data were examined using descriptive and inferential statistical analysis, such as independent t-test, Mann-Whitney U-test, Kruskal-Wallis test, and one-way ANOVA. The results indicate low satisfaction with blended learning on both sides: students and teachers. Furthermore, the data do not suggest differences in satisfaction between teachers and students, either in terms of the program taught or the university to which they belong. However, there were significant differences among students based on their age and their level of study. The paper also discusses the values, benefits, and restrictions of the mandatory blended learning approach applied by the Algerian ministry since March 2020. Implications and recommendations for both practitioners and researchers are additionally addressed in this study to make informed pedagogical choices in the future.

These days, face recognition systems are widely being employed in various daily applications such as smartphone unlocking, tracking school attendance, secure online bank transactions, smarter border control, to name a few. In spite of the remarkable progress, face recognition systems still suffer from occlusions, light variations, camera types, and their resolutions. Face recognition is still a dynamic research field. In this paper, we propose an efficient face recognition system based on the Gabor filter bank and a deep learning method known as Sparse AutoEncoder (SAE). The main aim of the proposed system is to improve the features extracted by the Gabor filter bank using the SAE method. Then, these enhanced features are subjected to features reduction using principal component analysis and linear discriminant analysis (PCA+LDA) technique. Finally, the matching stage is accomplished via cosine Mahalanobis distance. Experiments on seven publicly available databases (i.e., JAFFE, AT&T, Yale, Georgia Tech, CASIA, Extended Yale, Essex) show that the proposed system can achieve promising results with the combination of Gabor and SAE, as well as outperform previously proposed methods.

This paper present a novel system for person authentication based on score level fusion of Minor and Major dorsal finger knuckle patterns. In the proposed method, the adaptive single scale retinex method is used to extract the reflectance and the illumination of Major and Minor traits respectively, also the binarized statistical image features method is used to extract normalized histogram features. Furthermore, the Cosine Mahalanobis distance is used in the matching stage. Moreover, a multi-biometric system-based score level fusion has been proposed. In an attempt to enhance performance recognition, the symmetric sum-based rules based on triangular norms are applied. The system is evaluated on the publically Minor/Major knuckle database. Experiments conducted on this database achieved good results. Besides, the proposed system outperforms the previous methods given in the state of the art.

Palmprint recognition systems have been extensively studied over the past two decades because of their unique, accurate, and stable biometric features. Many researchers have investigated the two-dimensional (2D) palmprint recognition that contains texture information, but the 2D palmprint image does not contain three-dimensional (3D) depth information. To beat the limitations associated with a 2D palmprint recognition system; this paper proposes using both 2D and 3D palmprint features for a personal recognition system. The BSIF and GIST descriptors are utilized for feature extraction from the 2D and 3D palmprint. Then, the PCA + LDA technique is used to reduce the dimensionality of feature vectors. Next, the matching process is done using the Cosine distance. Finally, a score-level fusion was applied to get a final matching score using a fuzzy connective method based on the linear combination of triangular norms (T-norms and T-conforms). Also, the proposed method is compared to several techniques of score fusion, including Sum, Min, Max, and Symmetric Sum based on triangular norms. The system was evaluated on the publicly available Hong Kong-PolyU 2D + 3D palmprint database, and the results show the proposed system's efficiency.

This paper presents a new version of one of the models that we have proposed to measure the influence of web users in social networks like Facebook. The new version enhanced the previous one through the incorporation of two substantial modules, namely the global impression that the postings of the potential influencer get from his followers and the entropy which manifests the quantity of information carried by those postings. The comparison of our model with the precedent version and the PageRank benchmark has shown the effectiveness of our updates and the importance of incorporating the entropy and the global impression factors in its formulation.

During the last decade, traditional interpersonal relationships have been replaced by online communications due to the rapid evolution of online social networks. Trust plays an important role in enhancing interactions and ensuring security in such online communications. The decision to trust a user or not depends on a number of factors such as the similarity between users. The concept of user similarity is used in various fields for different aims. This paper presents an overview of the user similarity concept in an online trust-related context. We present various similarity metrics used by researchers in this field, and we provide a literature classification, including characteristics, data, and applications based on existing well-established studies. Finally, we review related work that focuses on both similarity and trust in online social networks.

The authentication of individuals based on Finger Knuckle print (FKP) is a very interesting system in the biometric community. In this paper, we introduce a biometric authentication system based on the FKP trait which consists of four stages. The first one is the extraction of the Region of Interest (ROI). The Phase Congruency method with Gabor filters bank descriptors has been used in the feature extraction stage. Then to enhance the performance of the proposed scheme the Principle Component Analysis (PCA) + Linear Discriminant Analysis (LDA) method has been used in the dimensionality reduction stage. Finally, cosine Mahalanobis distance has been used in the matching stage. Experiments were conducted on the FKP PolyU Database which are publicly available. The reported results with comparison to previous methods prove the effectiveness of the proposed scheme, as well as the given system can achieve very high performance in both the identification and verification modes.

Diabetic Retinopathy (DR) is one of the mainly causes of visual loss worldwide. In fact, DR is leading source of impaired vision in people between 25 and 74 years old. DR exists in wide ranged and its detection is a challenging problem. The gradual deterioration of retina leads to DR with several types of lesions, including hemorrhages, exudates, micro aneurysms, etc. Early detection and diagnosis can prevent and save the vision of diabetic patients or at least the progression of DR can be slowed down. The manual diagnosis and analysis of fundus images to substantiate morphological changes in micro aneurysms, exudates, blood vessels, hemorrhages, and macula are usually time-consuming and monotonous task. It can be made easy and fast with the help of computer-aided system based on advanced machine learning techniques that can greatly help doctors and medical practitioners. Thus, the main focus of this paper is to provide a summary of the numerous methods designed for discovering hemorrhages, microaneurysms and exudates are discussed for eventual recognition of non-proliferative diabetic retinopathy. This survey will help the budding researchers, scientists, and practitioners in the field.

Most minutiae-based matching techniques use local static descriptor to emphasize their discrimination power between ambiguous minutiae features. Despite the improvements shown by these methods, still some challenging problems limit their performance in particular the presence of spurious (added) minutiae and the missing of genuine minutiae. The added/missed minutiae problem misleads the matching process and complicates the correspondence decision. A general countermeasure of most existing matching algorithms is to add a global matching consolidation step that results in augmented time complexity. In this work, a dynamic minutiae-based descriptor is described. Its particularity resides in its ability to adjust a minutia features according to the correspondent minutia context in the second print. The minutiae of the input fingerprint are arranged to get a global stable geometric structure called minutiae-based polysegment structure (MPS). It permits to detect added/missed minutia once compared to another MPS structure. Whenever the matching algorithm detects an added minutia in an MPS, it inserts a virtual minutia in the second to update the minutia descriptor context and, hence, let propagating the similarity. This increases the chance to maximize the number of genuine paired minutiae. Furthermore, the MPS structure reduces enormously the minutiae space to be tested; the matching algorithm complexity is near O(n log(n)). Experiments of the proposed algorithm are conducted on the public database FVC2002.

Medical care has always presented quite wide ranged and challenging problems. However, machine learning techniques and methods as well as deep learning never stopped evolving and tackling those challenges issued by medicine, medical and health care. In order to have a more close up look on how machine learning and deep learning has been affecting medical care in general, we review in this paper some machine learning and deep learning techniques used in a variety of medical care sections such as medical imaging, medical decision, diagnostic, medical records and big data, and disease prediction.

Diabetes is a group of metabolic diseases in which a person has high blood sugar, either because the body does not produce enough insulin, or because cells do not respond to the insulin that is produced. The constant hyperglycemia of diabetes is related to long-haul harm, brokenness, and failure of various organs, particularly the eyes, kidneys, nerves, heart, and veins. This last can be monitoring by doctors over the internet and especially social net- works.In this context, having a healthcare social media strategy is no longer optional, it’s a requirement. With the right strategy, social media will become a powerful tool to build trust, reach more patients, and spread valuable medical information. Furthermore, advances in mobile technology and the widespread use of smartphones and tablets will make an improvement in healthcare services at a rapid pace.In this paper, we propose a system that supports a community of diabetes people, their families and friends, doctors, nutritionist and anyone who might need or offer help and support to the community. Our objective is to develop a system that can predict, diagnose and monitor the diabetes or support diabetes self- management using machine learning algorithms and Big Data.

In the last decade advances in wireless technology led to the emergence of a wide range of applications in healthcare, mobile health care, social networking, etc. Among these applications, health care, mobile health and smart health are considered the most promising and most important, this is mainly due to their positive impact on the quality of life of patients. Furthermore, mobile health care technology helps improve the quality of care administered to patients providing clinical and critical care in ways that help them follow-up their disease. Therefore, patients can be treated and cared for from anywhere, at any time. In addition mobility helps patients track their recovery with remote monitoring tools and follow what doctors prescribed. Thus we can conclude that this area of research is very interesting and this is why we intend to propose this special session in order to gather researchers in the field of mobile health care, give them the opportunity to share their ideas and conceptual approaches and finally discuss the recent advances in this field.

Social media users can easily be offended or hurt on those platforms, which leads to discomfort and health issues such as stress and anxiety. Forgiveness plays an important role to maintain healthy online relationships, which is the central constituent of social dynamics, from cooperation to social cohesion. While most prior studies have focused on analyzing forgiveness factors in offline settings using statistical methods, this study offers a new perspective using a two-staged approach whereby a research model was tested using structural equation modeling (SEM), and then the results were used as inputs for artificial neural network (ANN) and fuzzy logic (FL) models. An agent-based simulation was then performed to shed light on a possible use of the implemented models. Combining ANN and FL provided more accurate prediction results. In addition, simulation experiments call attention to the potential benefits of forgiveness in maintaining connectedness in a social network. The main purpose of this investigation was to evaluate the applicability of soft computing techniques on forgiveness prediction. Instead of relying on data mining techniques, we looked into questions that can improve our understanding of how society works in a digital age. In addition, this study provides an interesting example of a different and insightful way of doing computational social science that is useful to both researchers and practitioners.

This article describes how interpersonal relationships structures and standards are evolving. By focusing on a social network context, this study examined different factors that can affect forgiveness decision of a victim of an online offense. In addition, it inspected whether the decrease of trust after an online-related offense can be affected by forgiveness. 323 participants took part in this study by completing a questionnaire that recorded different measurements. Structural equation modeling was used as the main technique for data analysis, and AMOS was used as a tool. Surprisingly, while empathy and commitment had no significant direct effect, results showed that the severity of the offense, its frequency and pretransgression trust are the main factors that influence forgiveness. Moreover, a victim's trust towards the transgressor decreased much more in the absence of forgiveness than in its presence. A valuable contribution of this article is in the prospect for related future research as well as the potential for applications that explore new techniques to facilitate forgiveness in the digital age.

Obesity can be classified as one of the most dangerous diseases in the world, as the number of obese people keeps on increasing. Obesity is related to many chronic diseases such as cancer, type 2 diabetes and heart disease, also to many factors such as eating habits and inactivity. This last can be caused by people’s addiction to Internet and especially social networks. This research introduces a new approach in the daily fight against obesity, by proposing a system that supports a community of overweight people, obese people, their families and friends, physicians, and anyone who might need help and support from this community or who can offer help to members of the community. In addition to the new system proposed a specific purpose social network to support this community was developed in order to help them discuss their problems, express their specific needs, share their experiences and motivate other members by sharing their experience with obesity… etc.

This paper aims to describe a new simplistic model dedicated to gauge the online influence of Twitter users based on a mixture of structural and interactional features. The model is an additive mathematical formulation which involves two main parts. The first part serves to measure the influence of the Twitter user on just his neighbourhood covering his followers. However, the second part evaluates the potential influence of the Twitter user beyond the circle of his followers. Particularly, it measures the likelihood that the tweets of the Twitter user will spread further within the social graph through the retweeting process. The model is tested on a data set involving four kinds of real-world egocentric networks. The empirical results reveal that an active ordinary user is more prominent than a non-active celebrity one. A simple comparison is conducted between the proposed model and two existing simplistic approaches. The results show that our model generates the most realistic influence scores due to its dealing with both explicit (structural and interactional) and implicit features.

One of the biggest challenges teachers are facing is the inability of students to interact with each other. The instructor may ask for students' opinion, their ideas and whether they agree or disagree on a given problem or statement, without getting any feedback. However, some students have communication difficulties, and those who can have the correct answer may feel uncomfortable, and therefore the class will miss a good learning opportunity. Our objective is to create real-time multiple choice question system with an interactive and fun learning environment to increase the productivity of the maximum number of students.

Accurate singular point (SP) detection is an important factor in fingerprint (FP) recognition systems. We propose an algorithm to detect SPs in FP images. Our idea is based on the observation that the orientation field (OF) at the regions containing SPs has high variation, whereas in the other regions, it is smooth. Thus, a pixel-wise descriptor that comprises orientation-deviation (OD)-based features is proposed to measure the OF variation in the local neighborhood of a pixel which we call OF energy. Candidate SPs are characterized by locations where the OF energy function has local gradual maxima. Furthermore, the OD-based descriptor exhibits some advanced topological properties, in particular the descriptor profile tendency, which are highly correlated with the SP type. These properties are used to filter out some spurious SPs. A second refining step based on an extended Poincaré index is then applied to keep only genuine SPs with their information. The proposed algorithm has the ability to accurately detect the classical singularities as well as the arch-type SP. Experiments conducted over the public databases FVC2002 db1 and db2 confirm its accuracy and reliability with a reduced false alarm rate in comparison to other proposed methods.

Most of the solutions proposed to the security and privacy issues in mobile learning systems are generally inherited from those developed in e-learning systems and network communication background. However, the implication of the mobile devices in m-learning can reveal more private data and requires far more challenges. In this paper, we exploit the richness of mobile devices in sensors to propose a fingerprint-based strategy that provides a secure authentication, communication and non-repudiation scheme for mobile learning using recent advances in cancelable biometrics. The proposed scheme covers all the learning system steps starting b y subscription, communication and assessments.

E- learning is gaining more popularity due to the technological development and the personalization it offers for learners and organizations. Most e-learning platforms support group work and collaboration between learners, which is a desirable educational practice. Thus, virtual team members must be flexible to achieve their goals in a cooperative environment. In order to improve learners experiences, and to encourage collaboration between them, we propose and validate a theoretical model that predicts the effect of trust on learners' forgiveness when a conflict occurs in a virtual team.

We live in an interdisciplinary world, and we participate in an interplay between society and technology. In online settings, trust is required to back up successful interactions and to filter the overflow of information. However, trust is dynamic and very sensitive; it can be strengthened by positive experiences and destroyed by negative ones. Thus, we chose forgiveness as a way to repair broken trust relationships in computer-mediated communications. We believe that forgiveness benefits can improve online users' experiences by repairing broken relationships and encourage cooperation. In this paper, we present an overview about forgiveness research and we hope to put the first basic stones to drive more attention to this complicated concept in the digital environment.

There is a wealth of information created every day through computer-mediated communications. Trust is an important component to sustain successful interactions and to filter the overflow of information. The concept of trust is widely used in computer science in various contexts and for different aims. This variety can confuse or mislead new researchers who are interested in trust concept but not familiar enough with it to find relevant related work to their projects. Therefore, we give in this paper an overview of online trust by focusing on its social aspect, and we classify important reviewed work in an attempt to guide new researchers in this domain and facilitate the first steps of their research projects. Based on previous trust surveys, we considered the following criteria: (1) trust dimension and its research purpose, (2) the trusted context and (3) the application domain in which trust is applied.

Determining the identity of a person automatically is still an actual problem. There is an urgent need to have automatic and reliable authentication systems in order to combat fraud and meet the requirements for different areas ranging from international border stations to accessing personal information. Biometrics is an alternative to the old methods of identification. It involves identifying persons from their physical or behavioral characteristics. Face, fingerprint, iris, etc, are examples of physical characteristics. This course aims to introduce first basic concepts related to the recognition of individuals, based on their physiological or behavioral biometric characteristics, to students and allow them to study the key techniques to achieve reliable systems for biometric recognition. In This paper we will present the architecture of the course which will be held on a virtual laboratory. The course objective is to give the student different skills which are necessary in this field of study. The course is divided in several parts; each one will present a specific topic and will provide different notions in order to let students understand theoretical concepts by practicing.

E-learning is becoming more and more used by students and teachers in higher education. It is a new way of performing practical works and acquiring knowledge in many fields, especially in technology. Gathering ressourses and sharing their usage is very beneficial for educational institutions and will reduce the cost of training. In this paper we present the architecture of a platform we are developing in our university for the purpose of distance learning. This platform is a part of a TEMPUS project for linking three e-labs situated in three maghrebian countries, namely Algeria, Morocco and Tunisia. The platform is mainly dedicated to our students and can be accessed remotely via internet. We will present its architecture, focusing on the web interface and we will see that we use web services for access control and for simulations. The last will be performed by tools such as AMS and TCAD from Silvaco.

Social media and Social Network Analysis (SNA) acquired a huge popularity and represent one of the most important social and computer science phenomena of recent years. One of the most studied problems in this research area is influence and information propagation. The aim of this paper is to analyze the information diffusion process and predict the influence (represented by the rate of infected nodes at the end of the diffusion process) of an initial set of nodes in two networks: Flickr user’s contacts and YouTube videos users commenting these videos. These networks are dissimilar in their structure (size, type, diameter, density, components), and the type of the relationships (explicit relationship represented by the contacts links, and implicit relationship created by commenting on videos), they are extracted using NodeXL tool. Three models are used for modeling the dissemination process: Linear Threshold Model (LTM), Independent Cascade Model (ICM) and an extension of this last called Weighted Cascade Model (WCM). Networks metrics and visualization were manipulated by NodeXL as well. Experiments results show that the structure of the network affect the diffusion process directly. Unlike results given in the blog world networks, the information can spread farther through explicit connections than through implicit relations.

Several authors have shown that multimodality was a highly efficient solution for biometric identification and allows to increase performance and reliability. Indeed, the acquisition of multiple biometric features makes it much more difficult for an impostor to spoof the system with artificially developed samples. However, we do not get these benefits for free: multimodal biometric systems are less profitable and have significant effects on their users. Some of them may indeed lead a non acceptance by their users, in particular when it comes to privacy issues that may result when acquiring data at multiple levels. That is why it is always important to explore the possibility of finding new systems that could be accepted by users and which are fully reliable than the previous ones. In this paper we present a new approach for speaker biometric identification. This approach is a user friendly platform which adds a new modality, namely a virtual character, which will be easily accepted by users. The virtual character [6] will first put the users in a comfortable position and simultaneously acquire the information necessary for their identification. Then, it will guide them step by step until the end of the process of identification. The users are put in the best conditions which will facilitate their participation and acceptance to be identified.

A scheduling problem is organizing in time a set of activities, so as to satisfy a set of constraints and optimize the result. The temporal constraint modifies the project scheduling, therefore in loses its characteristics. Our objective is to solve this problem by finding the various types of temporal constraints then modeling them by using graphs. Furthermore we apply a technique for transforming an AoN graph (Activities on Nodes) which is unique and contains a significant number of arcs. This graph is not preferred by practitioners of project management. We transform the AoN graph into an AoA graph (Activities on Arcs) which contains fewer arcs and is preferred by practitioners of project management. In this paper we present some concepts of line graphs and an illustrative example of the proposed method.

Le problème d’ordonnancement consiste à organiser dans le temps un ensemble d’activités, de façon à satisfaire un ensemble de contraintes et optimiser le résultat. La contrainte temporelle touche au problème central de l’ordonnancement et le modifie, donc il n’aura plus ses caractéristiques. Notre travail consiste, pour résoudre ce problème, à modéliser par les graphes ce type de contraintes et le ramener à un problème classique d’ordonnancement ; ensuite appliquer une nouvelle technique de transformation d’un graphe AoN (Activities on Nodes) qui est unique avec un nombre important d’arcs et non préféré par les praticiens de gestion de projet vers un graphe AoA (Activities on Arcs) avec moins d’arcs et plus souhaitable. Le papier contient des concepts sur les graphes adjoints et un exemple illustratif de la méthode proposée.

Nowadays Person Recognition has got more and more interest especially for security reasons. The recognition performed by a biometric system using a single modality tends to be less performing due to sensor data, restricted degrees of freedom and unacceptable error rates. To alleviate some of these problems we use multimodal biometric systems which provide better recognition results. By combining different modalities, such us speech, face, fingerprint, etc., we increase the performance of recognition systems. In this paper, we study the fusion of speech and face in a recognition system for taking a final decision (i.e., accept or reject identity claim). We evaluate the performance of each system differently then we fuse the results and compare the performances.

In real applications of speaker verification [1] based on GMM-UBM method, the size of training data varies from a speaker to another; the choice of a common threshold of verification will reduce the performance of the system when we only have short records of training data. In this paper we first describe speaker verification using adapted gaussian mixture models based on Reynolds works [2] and the performance obtained by this method. We then propose a new method to estimate a speaker-dependent threshold and the results obtained by this approach.

The goal of this project is to bring together and integrates the work of the laboratory team members in order to get a practical realization of an Intelligent Multimodal Biometric Identification System. This last exploits the vocal and visual properties of a person to carry out, her or his, identification. To improve classification performance, the system will have a virtual character module which can exchange information with the person to be identified according to a random survey (based on information provided previously). Our first objective is to equip our laboratory with a powerful access control system able to identify the members of the lab and follows them where ever they go helping them with all kind of information they may be in need to.

Research in the field of face recognition knew considerable progress during these last years. Among the most evoked techniques we find those which employ the optimization of the size of the data in order to get a representation which makes it possible to carry out the recognition. For these methods, the images of faces are seen like points in a space of very great dimensions. The basic idea is to encode the initial data to pass to another space of dimensions much more reduced while preserving as much useful information. This paper presents a hybrid method combining principal components analysis (PCA) and the discrete cosine transform (DCT).

The proposed approach seeks to develop a combined simulation tool based on Petri nets, the producer consumer computing model and the simulation techniques. This tool is designated for simulating manufacturing systems. Such an approach offers an adequate platform to carry out simulation in parallel to take advantage of that, plus the experts of the Petri nets will find a strategy to make simulations not far from their concepts of modelling.
