摘要
介绍了反向传播网络算法(BackPropagationnetworkalgorithm,简称BP算法)的基本思想和存在的问题,阐述了增加动量项改进算法的实现方案,用VC++6.0实现的三层网络结构可改进算法的部分程序,并对这两算法的学习速度进行了测试和比较。
This paper introduces the basic thoughts and existing problems of the Back Propagation Network Algorithm （short for BP algorithm）, expounds the implementation scheme： of the improved algorithm by adding the item of the momentum, points out that the three-layer network structure realized with VC＋＋6.0 can improve partial programs of the algorithm, and makes test and comparison of the leaning speeds of the two algorithms. ：
