Title
(EN) METHOD AND SYSTEM FOR SELECTING PATTERN RECOGNITION TRAINING VECTORS
(FR) PROCEDE ET SYSTEME DE SELECTION DE VECTEURS D'APPRENTISSAGE A LA RECONNAISSANCE DE FORMES
Abstract
(EN) A computer-based method and system selects a plurality of training vectors for a pattern recognition system by creating a plurality of clusters (22) and then uniformly sampling the clusters. Each of the clusters is associated with a particular class and includes a plurality of example signals. The example signals are assigned to the clusters as a function of cluster-example distances (24). If a cluster includes one or more overlapping example signals, the number of clusters associated with the overlapping cluster is increased (28) and the example signals are re-assigned to the clusters.
(FR) La présente invention concerne un procédé et un système susceptibles de sélectionner des vecteurs d'apprentissage pour un système de reconnaissance des formes. On crée un ensemble de groupes (22) et on procède à l'échantillonnage desdits groupes. Chacun des groupes est apparenté à une classe particulière et comprend un ensemble de signaux d'exemple. Les signaux d'exemple sont affectés aux groupes en fonction des écarts (24) d'exemples par groupe. Si un groupe comporte un ou plusieurs signaux d'exemple semblables, le nombre de groupes apparentés au groupe ayant des signaux d'exemple semblables est incrémenté (28) et les signaux d'exemple sont réaffectés audits groupes.
