【Abstract】 The BP(back propagation) algorithm is a neural network learning algorithm, it is applied extensively in function approximation, mode distinguishing, classification, data compression et, but it has a question of convergence. In this paper, based on describing the principle of the BP algorithm, the convergence is discussed deeply, and several improvements to BP neural network are proposed.更多还原
