摘要
分析了自适应学习率BP算法,并对其进行了总结分类,针对每一类介绍了几种具体的自适应学习率BP算法。最后结合XOR问题把一种自适应学习率BP算法和标准BP算法进行了比较和评价。
The BP algorithm with adaptive learning rate is analyzed and then sorted into two groups. A few existing BP algorithms with adaptive learning rate are presented of each class. At last, a kind of BP algorithm with adaptive learning rate is evaluated and compared with standard BP algorithm by XOR problem.
