| Abstract: | In this paper, three kinds of modified BP algorithm are introduced. Through simulative calculation, their performance of convergent speeds and convergent precision are analysed and compared each other. The faetors that effect the network's convergence are discussed.It gives the user a reference to select a high performance algoiithm properly. |
