摘要
对传统的BP算法进行了改进,提出了基于二阶导数的BP算法,大大减少了样本训练的迭代次数,从而提高了网络运算速度.对异或问题和蜢虫分类问题的计算,取得了满意的效果.
A new BP algorithm with introduction of second derivative is proposed to improve the conventional BP algorithm. The iteration of training samples is reduced. The computation rate of the algorithm in the networks is raised. The algorithm is applied to discussing XOR problem and the classification of midges.
