Modèles Conjoints à Classes Latentes : étude empirique des propriétés du modèle et application dans le domaine de la sclérose latérale amyotrophique

Autor: Kyheng, Maéva

Publikováno v: Médecine humaine et pathologie. Université de Lille, 2023. Français. ⟨NNT : 2023ULILS007⟩

Joint latent class models allow the joint modeling of the evolution of a biomarker and the time to event. These models have the advantage of taking into account the heterogeneity (not explained by the covariates) that may exist for these data in the

Contributions to the Mathematical and Numerical Analysis of Multiscale Kinetic Equations

Autor: Rey, Thomas

Publikováno v: Numerical Analysis [math.NA]. Université de Lille, 2023

128 pages; This habilitation thesis covers a large part of the research I have carried out since the end of my PhD training. This work has been essentially aimed at modeling, analyzing and simulating systems composed of a large number of interacting

Optimization tools for non-asymptotic statistics in exponential families

Autor: Le Priol, Rémi

Les familles exponentielles sont une classe de modèles omniprésente en statistique. D'une part, elle peut modéliser n'importe quel type de données. En fait la plupart des distributions communes en font partie : Gaussiennes, variables catégorique

Analyse mathématique de certains modèles stochastiques de maladies infectieuses avec bruits blancs et sauts de Lévy

Autor: Sabbar, Yassine

Epidemiology offers apt means and tools to specify the degree to which risk factors and intervention strategies influence public health in the case of an epidemic outbreak. These manners include surveys, data analysis, controls, and appropriate asses

International audience; The direct numerical simulation of the acoustic wave scattering created by very small obstacles is very expensive, especially in three dimensions and even more so in time domain. The use of asymptotic models is very efficient

Problème de moments avec applications et estimations du spectre discret des opérateurs définis par des matrices infinies non bornées

Publikováno v: Analyse classique [math.CA]. Université du Littoral Côte d'Opale; Université Mohammed V (Rabat). Faculté des sciences, 2020. Français. ⟨NNT : 2020DUNK0563⟩

In this thesis, we first provide a concrete solution to the, almost all, quintic TCMP (that is, when m = 5). We also study the cardinality of the minimal representing measure. Based on the bi-variate recurrence sequence properties with some Curto-Fia

Marches aléatoires branchantes : Cas limites et hypothèses minimales

Autor: Boutaud, Pierre

Publikováno v: Probability [math.PR]. Université Paris-Saclay, 2020. English. ⟨NNT : 2020UPASM025⟩

The branching random walk is a particle system on the real line starting at time 0 with an initial particle at position 0, then each particle living at time n proceeds to die at time n+1 and give birth, independently from the other particles of gener

Asymptotic representation theory and applications to Yang-Mills theory

Autor: Lemoine, Thibaut

Publikováno v: Representation Theory [math.RT]. Sorbonne Université, 2020. English. ⟨NNT : 2020SORUS343⟩
Physique mathématique [math-ph]. Sorbonne Universite, 2020. Français

This thesis is devoted to the study of Yang–Mills measure on a compact surface, with structure group the unitary group U(N) or special unitary group SU(N). This study is more precisely about this measure’s asymptotic behaviour in the largeN limit
