| summary | Classification is an important field in data analysis. Prototype based methods like learning vector quantization (LVQ) and other provide an intuitive method which allows an understanding of the classification scheme, in contrast to multilayer perceptrons (MLPs) which work as a black box. Further, crisp classification some times in inadequate or impossble. Here fuzzy methods can help. We introduce extensions for supervised learning to the originally unsupervised prototype based neural vector quantizer self-organizing map (SOM) and neural gas (NG). Both approaches utilize neighbourhood cooperativness for improved convergence which is preserved in the supervised scheme, too. We demonstrate the approach for several examples including real world applications in bioinformatics. |
