Title: Multiple testing, classification and novelty detection

Time: Wed, Feb 9, 2011, 10am

Place: MPI für Molekulare Pflanzenphysiologie, Room 0.21 in The Box

It should not come as a surprise that there is a generic parallel between multiple (independent) tests and classification, since every test can be interpreted as a classification decision and vice-versa. The main difference, however, is in the way the problems are set up: classification assumes given labeled examples from both classes, while multiple testing generally assumes perfect knowledge of the null and no direct observation of the alternative; error criteria differ.

In this talk we will start with a review of some classical procedures for multiple testing with FDR control and discuss some recent results about procedures based on a so-called "rejection curve". In a second part we will proceed to study more precise connections to the theory of classification and novelty detection (sometimes also known as "one-class classification") and how, to some extent, one problem can be reduced to the other.
