METHOD AND DEVICE FOR PATTERN LEARNING AND PATTERN RECOGNITION USING ATTRACTION AND REPULSION, AND PATTERN LEARNING PROGRAM, PATTERN RECOGNITION PROGRAM AND RECORDING MEDIUM WITH THE PROGRAMS RECORDED

摘要

PROBLEM TO BE SOLVED: To learn/recognize the variation among images without intervention of a human or teacher signals. SOLUTION: A resultant force calculating means 2 calculates the mutual reaction of the attraction and the repulsion defined as factors of the distance or similarity in a plurality of image arrays. A merging means 3 executes the merging process for each image array without previous information on the category based on the dynamic stability of the cluster calculated with the two kinds of forces calculated by the resultant force calculating means 2. A splitting means 4 executes the splitting process for each merged image array based on the dynamic stability of the cluster calculated with the two kinds of forces calculated by the resultant force calculating means 2 to obtain new image arrays. A repeating means 5 repeats the processes of the merging means 3 and the splitting means 4 for each new image array to obtain a set of new images. A clustering means 6 automatically clusters the set of images obtained by the repeating means 5 by category.
