BP神经网络隐含层单元数的确定

Determining the number of BP neural network hidden layer units

本文针对BP神经网络隐含层单元数难以确定的问题,提出了一种改进的方法,并通过实验证明该方法有效的减少了验证次数,提高了确定隐含层最佳单元数的效率,具有较高的应用价值.

This paper puts forward an improved method to contrapose the problem which is difficult to determine the number of BP neural network hidden layer units. It is proved that the method is effective in reducing the frequency of test through experiments, and improves the efficiency of determining the best number of hidden layer units, which is more valuable in the applyication.
