BP学习算法的局限性与对策

Limitations and Countermeasures of BP Learning Algorithm

研究采用多神经网络组合结构、改进ＢＰ学习算法和训练策略等３个对策来克服ＢＰ学习算法的局限性．手写数字识别的实验研究表明，这些对策效果显著．

We present three countermeasures of using a composite structure of the mutiple neural network,improving BP learning algorithm and perfecting training tactics.By these countermeasures,the limitations of BP learning algorithm are overcome and good results in the recognition of hand-written digits arc obtained.
