Abstract

We develop a multilayer overlapped self-organizing maps (SOM's) with limited structure adaptation capabilities, and associated learning scheme for labeled pattern classification applications. The learning algorithm consists of the standard unsupervised SOM learning of synaptic weights as well as the supervised vector quantization learning. As higher layer SOMs overlap, the final classification is made by fusing the classifications of top-level overlapped SOMs. We obtained the best results ever reported for any SOM-based numerals classification system
