A few contributions to variable selection and nonparametric tests
Real-world data are often extremely high-dimensional, severely under constrained and interspersed with a large number of irrelevant or redundant features. Relevant... -
Feature selection from gene expression data : molecular signatures for breast...
Important developments in biotechnologies have moved the paradigm of gene expression analysis from a hypothesis-driven to a data-driven approach. In particular, DNA... -

Generalized Sobol sensitivity indices for dependent variables
A mathematical model aims at characterizing a complex system or process that is too expensive to experiment. However, in this model, often strongly non linear, input... -
A Markovian approach to distributional semantics
This thesis, which is organized in two independent parts, presents work on distributional semantics and on variable selection. In the first part, we introduce a new... -
