Thiesse, Jean-Marc. "Codage vidéo flexible par association d'un décodeur intelligent et d'un encodeur basé optimisation débit-distorsion". Nice, 2012. http://www.theses.fr/2012NICE4058.
This Ph. D. Thesis deals with the improvement of video compression efficiency. Both conventional and breakthrough approaches are investigated in order to propose efficient methods for Intra and Inter coding dedicated to next generations video coding standards. Two tools are studied for the conventional approach. First, syntax elements are cleverly transmitted using a data hiding based method which allows embedding indices into the luminance and chrominance residuals in an optimal way, rate-distortion wise. Secondly, the large motion redundancies are exploited to improve the motion vectors coding. After a statistical analysis of the previously used vectors, an accurate forecast is performed to favor some vector residuals during a last step which modifies the original residual distribution. 90% of the coded vectors are efficiently forecasted by this method which helps to significantly reduce their coding cost. The breakthrough approach comes from the observation of the H. 264/AVC standard and its successor HEVC which are based on a predictive scheme with multiple coding choices, consequently future improvements shall improve texture by extensively using the competition between many coding modes. However, such schemes are bounded by the cost generated by the signaling flags and therefore it is required to transfer some decisions to the decoder side. A framework based on the determination of encoding parameters at both encoder and decoder side is consequently proposed and applied to Intra prediction modes on the one hand, and to the emerging theory of compressed sensing on the other hand. Promising results are reported and confirm the potential of such an innovative solution
Dehman, Alia. "Spatial clustering of linkage disequilibrium blocks for genome-wide association studies". Thesis, Université Paris-Saclay (ComUE), 2015. http://www.theses.fr/2015SACLE013/document.
With recent development of high-throughput genotyping technologies, the usage of Genome-Wide Association Studies (GWAS) has become widespread in genetic research. By screening large portions of the genome, these studies aim to characterize genetic factors involved in the development of complex genetic diseases. GWAS are also based on the existence of statistical dependencies, called Linkage Disequilibrium (LD) usually observed between nearby loci on DNA. LD is defined as the non-random association of alleles at different loci on the same chromosome or on different chromosomes in a population. This biological feature is of fundamental importance in association studies as it provides a fine location of unobserved causal mutations using adjacent genetic markers. Nevertheless, the complex block structure induced by LD as well as the large volume of genetic data arekey issues that have arisen with GWA studies. The contributions presented in this manuscript are in twofold, both methodological and algorithmic. On the methodological part, we propose a three-step approach that explicitly takes advantage of the grouping structure induced by LD in order to identify common variants which may have been missed by single marker analyses. In thefirst step, we perform a hierarchical clustering of SNPs with anadjacency constraint using LD as a similarity measure. In the second step, we apply a model selection approach to the obtained hierarchy in order to define LD blocks. Finally, we perform Group Lasso regression on the inferred LD blocks. The efficiency of the proposed approach is investigated compared to state-of-the art regression methods on simulated, semi-simulated and real GWAS data. On the algorithmic part, we focus on the spatially-constrained hierarchical clustering algorithm whose quadratic time complexity is not adapted to the high-dimensionality of GWAS data. We then present, in this manuscript, an efficient implementation of such an algorithm in the general context of anysimilarity measure. By introducing a user-parameter $h$ and using the min-heap structure, we obtain a sub-quadratic time complexity of the adjacency-constrained hierarchical clustering algorithm, as well as a linear space complexity in thenumber of items to be clustered. The interest of this novel algorithm is illustrated in GWAS applications

The advent of high-throughput genotyping nowadays allows better exploitation of the association phenomenon, called linkage disequilibrium (LD), between alleles of different loci on the genome. In this context, the usefulness of some models to fine map quantitative trait locus (QTL) is questioned. The aims of this work were to discriminate between models routinely used for QTL mapping and to provide enlightenment on the best way to exploit LD, when using haplotypes, in order to optimize haplotype-based models. We show that single-marker linkage models, developed twenty years ago, have little interest today with the advent of high-throughput genotyping. In this context, we show that single-marker association models are more advantageous than single-marker linkage models, especially for QTL with a small or moderate effect on the phenotype. The statistical powers and robustness of these models have been studied both theoretically and by simulations, in order to validate the comparison of single-marker association models with single-marker linkage models. However, single-marker models are less efficient than haplotype-based models for making better use of LD in fine mapping of QTL. Mathematical properties related to the multiallelic LD captured by haplotype-based models have been shown, and studied, by the use of a matrix distance defined between two loci on the genome. This distance has been expressed algebraically as a function of the multiallelic LD coefficients. The mathematical properties related to this function show that it is difficult to exploit well multiallelic LD, for a high-throughput genotyping, if one takes into account the partial and total similarity between haplotypes instead of the total similarity only. Studies on real and simulated data illustrate these properties and show a correlation above 0.9 between a statistic based on the matrix distance and mapping results. Hence a new method, based on the matrix distance, which helps to discriminate between models used for mapping is proposed

Après une description introductive des principales problématiques liées aux études d'association à grande échelle, nous abordons plus particulièrement les approches simple-marqueur avec une étude de puissance des principaux tests d'association, ainsi que de leur combinaisons. Nous considérons ensuite l'utilisation d'approches multi-marqueurs avec le développement d'une méthode d'analyse fondée à partir de la statistique du Score Local. Celle-ci permet d'identifier des associations statistiques à partir de régions génomiques complètes, et non plus des marqueurs pris individuellement. Il s'agit d'une méthode simple, rapide et flexible pour laquelle nous évaluons les performances sur des données d'association à grande échelle simulées et réelles. Enfin ce travail traite également du problème du test-multiple, lié aux nombre de tests à réaliser lors de l'analyse de données génétiques ou génomiques haut-débit. La méthode que nous proposons à partir du Score Local prend en compte ce problème. Nous évoquons par ailleurs l'estimation du Local False Discovery Rate à travers un simple modèle de mélange gaussien.
L'ensemble des méthodes décrites dans ce manuscrit ont été implémentées à travers trois logiciels disponibles sur le site du laboratoire Statistique et Génome : fueatest, LHiSA et kerfdr.
Slim, Lotfi. "Detection of epistasis in genome wide association studies with machine learning methods for therapeutic target identification". Thesis, Université Paris sciences et lettres, 2020. https://pastel.archives-ouvertes.fr/tel-02895919.
By offering an unprecedented picture of the human genome, genome-wide association studies (GWAS) have been expected to fully explain the genetic background of complex diseases. So far, the results have been mitigated to say the least. This, among other things, can be partially attributed to the adopted statistical methodology, which does not often take into account interaction between genetic variants, or epistasis. The detection of epistasis through statistical models presents several challenges for which we develop in this thesis a pair of adequate tools. The first tool, epiGWAS, uses causal inference to detect epistatic interactions between a target SNP and the rest of the genome. The second tool, kernelPSI, instead uses kernel methods to model epistasis between nearby single-nucleotide polymorphisms (SNPs). It also leverages post-selection inference to jointly perform SNP-level selection and gene-level significance testing. The developed tools are -- to the best of our knowledge -- the first to extend powerful statistical learning frameworks such as causal inference and nonlinear post-selection inference to GWAS. In addition to the methodological contributions, a special emphasis was placed on biological interpretation to validate our findings in multiple sclerosis and body-mass index variations

This thesis deals with the study of asymptotic properties of e kernel (Parzen-Rosenblatt) density estimate under associated and censored model. In this setting, we first recall with details the existing results, studied in both i.i.d. and strong mixing condition (α-mixing) cases. Under mild standard conditions, it is established that the strong uniform almost sure convergence rate, is optimal. In the part dedicated to the results of this thesis, two main and original stated results are presented : the first result concerns the strong uniform consistency rate of the studied estimator under association hypothesis. The main tool having permitted to achieve the optimal speed, is the adaptation of the Theorem due to Doukhan and Neumann (2007), in studying the term of fluctuations (random part) of the gap between the considered estimator and the studied parameter (density). As an application, the almost sure convergence of the kernel mode estimator is established. The stated results have been accepted for publication in Communications in Statistics-Theory & Methods ; The second result establishes the asymptotic normality of the estimator studied under the same model and then, constitute an extension to the censored case, the result stated by Roussas (2000). This result is submitted for publication
