Titre :<\/strong> Vers de nouveaux d\u00e9fis en apprentissage statistique et en science des donn\u00e9es<\/p>\n

\nO\u00f9:<\/strong> En salle G09, \u00e0 T\u00e9l\u00e9com SudParis (Evry)<\/p>\n

R\u00e9sum\u00e9 :<\/strong> L’expos\u00e9 est consacr\u00e9 \u00e0 l’analyse des donn\u00e9es massives pour lesquelles la repr\u00e9sentation classique des variables a des limites. Il existe actuellement un nombre cons\u00e9quent de m\u00e9thodes de clustering, mais elles ne s’adaptent pas toujours aux particularit\u00e9s de certains types de donn\u00e9es (cat\u00e9gorielles, binaires, mixtes, s\u00e9quences, flux, …). On distinguera deux familles de mod\u00e8les de classification non supervis\u00e9e topologique: les mod\u00e8les probabilistes et les mod\u00e8les \u00ab\u00a0d\u00e9terministes\u00a0\u00bb. L’expos\u00e9 abordera \u00e9galement des travaux r\u00e9cent sur l’apprentissage statistique scalable en utilisant les nouveaux paradigmes (Mapreduce…). En plus des difficult\u00e9s soulev\u00e9es par la vari\u00e9t\u00e9 des donn\u00e9es dans la mouvance du Big data et des open data accompagn\u00e9e par des plateformes nouvelles qui offrent un acc\u00e8s facile et lisible \u00e0 l’information relationnelle, de nouveaux d\u00e9fis en apprentissage statistique sont ouverts.<\/p>\n

Biographie<\/strong>
\nMustapha LEBBAH est ma\u00eetre de conf\u00e9rences \u00e0 l’universit\u00e9 de Paris 13 depuis 2005 et HdR en 2012. Il est membre permanent de l\u2019\u00e9quipe \u00ab\u00a0Apprentissage Artificiel et Applications\u00a0\u00bb du laboratoire d’Informatique de l\u2019Universit\u00e9 Paris Nord et du CNRS. Son th\u00e8me de recherche principal concerne les syst\u00e8mes d\u2019apprentissage automatique pour le traitement et la visualisation des donn\u00e9es massives et complexes. Un de ses axes de recherche concerne la classification probabiliste non supervis\u00e9e \u00e0 base de mod\u00e8les de m\u00e9langes et mod\u00e8les topologiques. Un autre axe de recherche concerne le passage \u00e0 l\u2019\u00e9chelle et l’apprentissage statistique massivement distribu\u00e9 et scalable. Mustapha Lebbah est aussi secr\u00e9taire de la Soci\u00e9t\u00e9 Francophone de Classification (SFC), membre \u00e9lu du bureau de l\u2019association EGC (Extraction et Gestion des Connaissances) et du bureau du groupe \u00ab\u00a0Data Mining et Apprentissage\u00a0\u00bb de la SFdS (Soci\u00e9t\u00e9 Fran\u00e7aise de Statistique).<\/p>\n","protected":false},"excerpt":{"rendered":"
