| Abstract: | Feature selection is an important step in fault diagnosis owing to its considerable reduction in redundant features to enhance the effect of diagnosis. In view of the deficiencies of traditional combination optimization method, a new method based on genetic algorithm is proposed in the paper. According to the results of computer simulation and practical diagnosis example, it is proved that this method possess excellent parallelism and optimization property. |
