Abstract

A method for generating a self-organizing map of line images is proposed. In the proposed method, called the NG×SOM, a set of data distributions is represented by a product space organized by a set of neural gas networks (NGs) and a self-organizing map (SOM). In this paper, it is assumed that the line images dealt with by the NG×SOM have the same, yet unknown, topology. Thus the task of the NG×SOM is to generate a map of line images with the same topology, in which the images are continuously and naturally morphed from one into another. We applied the NG×SOM to a handwritten character recognition task. The results obtained show that this method is effective, particularly when the number of training data is small.
