Important developments in biotechnologies have moved the paradigm of gene expression analysis from a hypothesis-driven to a data-driven approach. In particular, DNA microarrays make it possible to measure gene expression on a genome-wide scale, leaving its analysis to statisticians.From these high-dimensional data, we contribute, in this thesis, to two biological problems. Both questions are considered from the supervised learning point of view. In particular, we see them as feature selection problems. Feature selection consists in extracting variables - here, genes - that contain relevant and sufficient information to predict the answer to a given question.First, we are concerned with selecting lists of genes, otherwise known as molecular ...
