| Abstract: | A sample feature selecting method for pattern classification based on rough sets is presented in this paper. Features are selected from the given training data by applying the theory and method of rough sets. Neural networks are constructed and trained according to these features, and trained networks are used to classify the other data on the basis of these features. In the pattern classification, this method can reduce the training times of neural networks and improve the generalization ability of networks. |
