Abstract: Competitive neural network has been widely used in the pattern recognition，classification and other aspects，and shows the great advantages compared with the traditional clustering methods.But the competitive neural network is still inadequate in many aspects，and needs to be further improved.Through the introduction of threshold value learning rules，this paper resolves the issue of getting the training error in the face of such network’s blind spot，on the basis of Kohonen’s Learning Vector Quantization Network（LVQ）.Finally this paper programs the realization by Matlab.

Key words: Learning Vector Quantization Network（LVQ）, threshold value, blind spot
