【Abstract】 Self organizing neural networks, also called unsupervised learning networks, may learn from the environment automatically, and therefore, possess stronger ability to learn adaptively. At present, self organizing neural networks have gotten wider and wider applications in the fields of image understanding,pattern recognition and intelligent robots. But, because of the single criterion learning algorithm used in self organizing neural networks, the learning efficiency of self organizing neural networks is low, which has affected the wider application of self organizing neural networks. This paper presents a kind of multi criteria learning method based on fuzzy entropy criterion and error squared sum criterion, which may overcome, to some extent, the limitations of single criterion. Experiment results have shown its advantages and effectiveness in both learning efficiency and neural network optimization.更多还原
