Abstract

Most unsupervised learning algorithms ignore prior application knowledge. Also, Self Orgnanized Maps (SOM) based approaches usually develop topographic maps with disjoint and uniform activation regions that correspond to a hard clustering of the patterns at their nodes. We present a novel Self-Organizing map that adapts its parameters in kernel space, grows dynamically up to a size defined with statistical criteria and is capable of incorporating a priori information in the form of a supervised bias at the cluster formation.
