Quem alimenta Paris?

Université Paris Diderot — Paris 7

This thesis deals with statistical questions raised by the analysis of highdimensional genomic data for cancer research. In the first part, we study asymptotic properties of multiple testing procedures that aim at controlling the False Discovery Rate (FDR), that is, the expected False Discovery Proportion (FDP) among rejected hypotheses. We develop a versatile formalism to calculate the asympto...

An Achievement Test for Knowledge-Based Systems: QUEM

This paper describes QUEM, a method for assessing the skill level of a knowledge-based system based on the quality of the solutions it produces. QUEM is demonstrated by using it to assess the performance of a particular knowledge-based system, P. QUEM can be viewed as an achievement or job placement test given to know ledge-based systems to help system designers determine how the system should ...

QUEM: An Achievement Test for Knowledge-Based Systems

This paper describes the QUality and Experience Metric (QUEM), a method for estimating the skill level of a knowledgebased system based on the quality of the solutions it produces. It allows one to assess how many years of experience the system would be judged to have if it were a human by providing a quantitative measure of the system’s overall competence. QUEM can be viewed as a type of achie...

Quem somos nós: os Wari ́ encontram os Brancos

Université Paris -

The high bb cross section produced by the LHC offers an excellent opportunity for the study of flavour changing neutral current B decays, where the effects of new physics can be probed. This thesis presents an analysis of the rare decay B→ K∗0e+e−, which can be used to measure the polarisation of the photon in the b→ sγ transition. When the dilepton mass is low, the e+e− pair comes predominantl...
