几种变学习率的快速BP算法比较研究

Contrast Study of Several Fast BP Algorithms with Variable Learning Rate

首先将作者见到的各种变学习率的快速ＢＰ算法分成了３类；然后针对两类不同的问题对它们进行了大量的对比实验研究；根据实验结果指出，对各种以变学习率为基础的快速ＢＰ算法，应视具体应用问题慎重选择。

In this paper,various fast BP algorithms with variable learning rate are divided into three classes.The performances of them are studied through contrast experiments.Some results are given from the experiments.The various fast BP algorithms must be chosen carefully accorrding to the applied problem.
