Abstract

L'invention concerne un classificateur à arbres de décision (20). Ce dernier est conçu à l'aide du modèle de Markov caché pour produire un classificateur final qui peut être mis en oeuvre sans utiliser d'opérations mathématiques. L'appareil, selon la présente invention, déplace tous les calculs mathématiques vers la construction de l'arbre de décision. Une fois cette opération terminée, l'arbre de décision peut être mis en oeuvre uniquement à l'aide d'opérations logiques comme des opérations de comparaisons binaires et d'adressage de mémoire. Cette simplicité permet d'utiliser l'arbre de décision dans une simple forme de matériel à l'aide de portes traditionnelles.
