| Abstract: | Theory and algorithms of clustering neural network are discussed. The gen-eralized LVQ neural network was aimed to improve the algorithm of LVQ. However it brought another problem. GLVQ-F algorithm was an improvement to GLVQ, but it was still unstable and left the problem of LVQ unsolved. The defect of GLVQ-F clustering neural network algorithm is theoretically analyzed in this paper, and the modified theory is discussed. Finally, a modified neural network algorithm of competitive learn-ing schemes (MLVQ) is given. Experiment results show the new algorithm is stable and effective. |
