摘要
本文对ｓｉｇｍｏｉｄ函数的陡度、学习速率、动量因子等的选取进行探讨，分析它们对收敛速度的影响，提出一些选取时应考虑的问题。在模糊控制规则生成和智能控制应用中证明本文提出的ＢＰ算法参数选取方法能有效地缩短训练时间。
In this paper the choice of BP algorithm parameters, such as the slope of sigmoid function,learning rate ,moment factor, etc are discussed. Factor that affect convergency are analyzed. Some issues thatmust be considered when choosing BP a1gorithm parameters are presented. In fuzzy control rules generationand intelligent control application choosing methods of BP al8orithm parameters that author slyes can obviously decrease training time.
