摘要
ＢＰ网络现在得到了广泛的应用。然而对于学习样本较多、输入输出映射关系复杂的情况，学习速度较慢。我们分析了网络误差曲面特征，提出了快速ＢＰ算法，它可以大幅度地提高学习速度。
BP network is now widely used.However,its learning speed is slow in learning more advanced copies and a complicated output-input projection relationship.The authors analyze the characteristics of the network error curved surface and present a rapid BP algorithm which can improve the learning speed greatly in this paper.
