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。通过分析网络误差曲面特征,提出了快速BP算法,它可以大幅度地提高学习速度。
BP network 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.
