摘要
研究了 BP神经网络的算法 ,提出了权值、阈值调整的双动量算法和学习率调整的批处理半恢复自适应调整法 ,使网络总体收敛性较好 ;用所设软件计算了 1
We studied the calculation method of BP neural networks,presented the calculation method for the double momentum items adjusting weight and bias values,and offered the half recovering self adapting adjustment method for adjusting learning rate after calculating a batch of sample data. Generally, the neural networks have an excellent calculation convergence.Based on the BP neural networks,We calculated 15 covalent bond length in the molecules containing hydrogen atoms with satisfied results.
