| Abstract: | In the application of artificial neural network, BP network is more often used than others. In this paper, the basic structure and algorithm of the BP network are briefly introduced and its disadvantages discussed. Accordingly, two methods to improve the generalization ability of BP network are presented, and through an example, their applicability is analyzed. |
