Abstract

Apres avoir empiriquement mis en evidence l'instabilite des procedures CART de classification par arbre, nous presentons des methodes d'agregation de classificateurs obtenues a l'aide d'un reechantillonage de type bootstrap. Enfin, nous mettons en oeuvre ces procedures sur un probleme de prevision quotidienne de pic de pollution en ozone.
