Statistics Seminar on "Image classification: A (new) statistical viewpoint" Abstract : In this talk we consider a simple supervised classification problem for object recognition on grayscale images. There are two possible perspectives to solve this problem. Firstly, one can interpret object recognition as a high-dimensional classification problem, where every pixel is a variable.

WORKSHOP by Christian Ritter (UCLouvain) "Interesting Internet Data Sources" Abstract: In this talk, I shall visit a collection of internet sources to find data about important subjects in health, wealth, environment, and life in general. This will include the Gapminder, Eurostat, Statistics Belgium, Healthdata.Org, IRCELINE and Sciensano.

  "Projecting prevalence rates by Age-Period-Cohort models for the Belgian population - opportunities and pitfalls" Abstract: Repeated cross-sectional health interview surveys provide important information on the health status of a specific region.

"How good is your Laplace approximation? Finite-sample error bounds for a variety of useful divergences" Abstract :The Laplace approximation is a popular method for providing mean and variance estimates for a Bayesian posterior. But can we trust these estimates for practical use?

 WORKSHOP by Bernadette Govaerts (UCLouvain) "Combinaison de méthodes de tests multiples et multivariées pour la modélisation de données -omiques issues d’un plan expérimental" Résumé: De nombreuses technologies modernes sont utilisées pour analyser des échantillons issus de plans expérimentaux en particulier  dans les domaines médical, biologique, chimique ou agronomique.

WORKSHOP by Marie Chion (University of Cambridge) "Données manquantes et imputation : application à la protéomique quantitative" Résumé: En statistique, une valeur est dite manquante lorsqu’elle n’est pas observée. Elle peut être due à une non-réponse ou à des problèmes expérimentaux par exemple. Les techniques courantes d’analyse statistique reposent sur des jeux de données complets.
