| Abstract: | Aimed to the problem that original feature is mass and redundancy in pattern recognition,a method of feature optimal based on genetic algorithm is proposed.This paper describes the general idea of genetic algorithm.Then explains and designs a fitness function and genetic operators.Simulations results show that this method has good performance in both the quality of obtained feature subset and efficiency. |
