| Abstract: | BP network has been extensively applied.Nevertheless,under the condition of numerous learning samples and complicated input output mapping relationship,the learning speed is rather low.Based on analysing characteristics of error curved surface of the network,the authors have advanced the rapid BP algorithm,which can greatly raise the learning speed. |

| Keywords: | error curved surface BP network learning rate |
