Full textLa première partie est centrée sur l'analyse des réseaux et fait un point critique sur les réseaux étudiés et les paramètres introduits pour mieux comprendre leur structure. Un certain nombre de ces paramètres sont partagés par la majorité des réseaux étudiés et justifient l'étude de ceux-ci de manière globale.
La seconde partie qui constitue le coeur de cette thèse s'attache à la modélisation des grands réseaux d'interactions, c'est-à-dire la construction de graphes artificiels semblables à ceux rencontrés en pratique. Ceci passe tout d'abord par la présentation des modèles existants puis par l'introduction d'un modèle basé sur certaines propriétés non triviales qui est suffisamment simple pour que l'on puisse l'étudier formellement ses propriétés et malgré tout réaliste.
Enfin, la troisième partie est purement méthodologique. Elle permet de présenter la mise en pratique des parties précédentes et l'apport qui en découle en se basant sur trois cas particuliers : une étude des échanges dans un réseau pair-à-pair, une étude de la robustesse des réseaux aux pannes et aux attaques et enfin un ensemble de simulations visant à estimer la qualité des cartes de l'Internet actuellement utilisées.
Cette thèse met en lumière la nécessité de poursuivre les travaux sur les grands réseaux d'interactions et pointe plusieurs pistes prometteuses, notamment sur l'étude plus fine des réseaux, que ce soit de manière pondérée ou dynamique. Mais aussi sur la nécessité d'étudier de nombreux problèmes liés à la métrologie des réseaux pour réussir à capturer leur structure de manière plus précise.

Full textOver the last two decades, network structure analysis has experienced rapid growth with its construction and its intervention in many fields, such as: communication networks, financial transaction networks, gene regulatory networks, disease transmission networks, mobile telephone networks. Social networks are now commonly used to represent the interactions between groups of people; for instance, ourselves, our professional colleagues, our friends and family, are often part of online networks, such as Facebook, Twitter, email. In a network, many factors can exert influence or make analyses easier to understand. Among these, we find two important ones: the time factor, and the network context. The former involves the evolution of connections between nodes over time. The network context can then be characterized by different types of information such as text messages (email, tweets, Facebook, posts, etc.) exchanged between nodes, categorical information on the nodes (age, gender, hobbies, status, etc.), interaction frequencies (e.g., number of emails sent or comments posted), and so on. Taking into consideration these factors can lead to the capture of increasingly complex and hidden information from the data. The aim of this thesis is to define new models for graphs which take into consideration the two factors mentioned above, in order to develop the analysis of network structure and allow extraction of the hidden information from the data. These models aim at clustering the vertices of a network depending on their connection profiles and network structures, which are either static or dynamically evolving. The starting point of this work is the stochastic block model, or SBM. This is a mixture model for graphs which was originally developed in social sciences. It assumes that the vertices of a network are spread over different classes, so that the probability of an edge between two vertices only depends on the classes they belong to

Full textThe main goal of our research was to characterize the individuals connected in a social network by analyzing the local structure of the network. For that, we proposed a method that describes the way a node (corresponding to an individual) is embedded in the network. Our method is related to the analysis of egocentred networks in sociology and to the local approach in the study of complex networks. It can be applied to small networks, to fractions of networks and also to large networks, due to its small complexity. We applied the proposed method to two large social networks, one modeling online activity on MySpace, the other one modeling mobile phone communications. In the first case we were interested in analyzing the online popularity of artists on MySpace. In the second case, we proposed and used a method for clustering nodes that are connected in a similar way to the network. We found that the distribution of mobile phone users into clusters was correlated to other characteristics of the individuals (i. E. Communication intensity and age). Although in this thesis we applied the two methods only to social networks, they can be applied in the same way to any other graph, no matter its origin

Full textGraphs are ubiquitous in many fields of research ranging from sociology to biology. A graph is a very simple mathematical structure that consists of a set of elements, called nodes, connected to each other by edges. It is yet able to represent complex systems such as protein-protein interaction or scientific collaborations. Graph clustering is a central problem in the analysis of graphs whose objective is to identify dense groups of nodes that are sparsely connected to the rest of the graph. These groups of nodes, called clusters, are fundamental to an in-depth understanding of graph structures. There is no universal definition of what a good cluster is, and different approaches might be best suited for different applications. Whereas most of classic methods focus on finding node partitions, i.e. on coloring graph nodes so that each node has one and only one color, more elaborate approaches are often necessary to model the complex structure of real-life graphs and to address sophisticated applications. In particular, in many cases, we must consider that a given node can belong to more than one cluster. Besides, many real-world systems exhibit multi-scale structures and one much seek for hierarchies of clusters rather than flat clusterings. Furthermore, graphs often evolve over time and are too massive to be handled in one batch so that one must be able to process stream of edges. Finally, in many applications, processing entire graphs is irrelevant or expensive, and it can be more appropriate to recover local clusters in the neighborhood of nodes of interest rather than color all graph nodes. In this work, we study alternative approaches and design novel algorithms to tackle these different problems. The novel methods that we propose to address these different problems are mostly inspired by variants of modularity, a classic measure that accesses the quality of a node partition, and by random walks, stochastic processes whose properties are closely related to the graph structure. We provide analyses that give theoretical guarantees for the different proposed techniques, and endeavour to evaluate these algorithms on real-world datasets and use cases

Full textIn this thesis, we study data analysis algorithms using random walks on neighborhood graphs, or random geometric graphs. It is known random walks on such graphs approximate continuous objects called diffusion processes. In the first part of this thesis, we use this approximation result to propose a new soft clustering algorithm based on the mode seeking framework. For our algorithm, we want to define clusters using the properties of a diffusion process. Since we do not have access to this continuous process, our algorithm uses a random walk on a random geometric graph instead. After proving the consistency of our algorithm, we evaluate its efficiency on both real and synthetic data. We then deal tackle the issue of the convergence of invariant measures of random walks on random geometric graphs. As these random walks converge to a diffusion process, we can expect their invariant measures to converge to the invariant measure of this diffusion process. Using an approach based on Stein's method, we manage to obtain quantitfy this convergence. Moreover, the method we use is more general and can be used to obtain other results such as convergence rates for the Central Limit Theorem. In the last part of this thesis, we use the concept of persistent homology, a concept of algebraic topology, to improve the pooling step of the bag-of-words approach for 3D shapes

Full textWith the increasing availability of large amounts of data, computational complexity has become a keystone of many machine learning algorithms. Stochastic optimization algorithms and distributed/decentralized methods have been widely studied over the last decade and provide increased scalability for optimizing an empirical risk that is separable in the data sample. Yet, in a wide range of statistical learning problems, the risk is accurately estimated by U-statistics, i.e., functionals of the training data with low variance that take the form of averages over d-tuples. We first tackle the problem of sampling for the empirical risk minimization problem. We show that empirical risks can be replaced by drastically computationally simpler Monte-Carlo estimates based on O(n) terms only, usually referred to as incomplete U-statistics, without damaging the learning rate. We establish uniform deviation results and numerical examples show that such approach surpasses more naive subsampling techniques. We then focus on the decentralized estimation topic, where the data sample is distributed over a connected network. We introduce new synchronous and asynchronous randomized gossip algorithms which simultaneously propagate data across the network and maintain local estimates of the U-statistic of interest. We establish convergence rate bounds with explicit data and network dependent terms. Finally, we deal with the decentralized optimization of functions that depend on pairs of observations. Similarly to the estimation case, we introduce a method based on concurrent local updates and data propagation. Our theoretical analysis reveals that the proposed algorithms preserve the convergence rate of centralized dual averaging up to an additive bias term. Our simulations illustrate the practical interest of our approach

Full textDecentralised collaborative applications address privacy, availability and security issues related to centralised collaborative platforms. Such applications are based on a peer-to-peer communication paradigm according to which all users are directly connected to one another. Collaborations tend to widen and spread beyond the borders of organisations. Under these circumstances, it is necessary to guarantee to users the control over their data, while keeping collaboration available. To that end, the social network that has built between collaborators may be used as topology. Lack of information on this trusted network leads us to develop an approach to study its morphological properties. In this thesis, we develop and implement an approach to study the social structure of interactions in the context of inter-organisational collaborations. We propose a stochastic approach based on Exponential Random Graph Models (ERGM) and spatial models. We define a formalism that highlights the structure of interactions and integrates the organisational dimension. We propose to use a Bayesian inference method, ABC Shadow, to overcome the issues related to the parameters estimation. This approach is applied to a real case study: the collaborations initiated by researchers in a laboratory. In particular, it highlights the low tendency for a researcher to create collaborative links with other laboratories. We show that this approach can be applied to other kinds of social interactions, such as interactions between pupils of a primary school. Finally, we present a parallelisation strategy of the Gibbs sampler aimed at processing larger graphs in a reasonable time
