The Study of the Optimal Structure of BP Nueral Network
BP 神经网络网络结构优化问题的研究

The acting mechanism of the BP Neural Network's hidden units and the number's choice have been a difficult promble on the study of BP Nueral Network.By using the grey correlation analaysis on the hidden units number's determination of the BP Nueral Network,this method realized the optimal of BP Nueral Network,and also improve network's forecasting accuracy.Its simulated result shows that the method is effective.At the same time,it also afford a new thinking to us for a further study of the BP Nueral Network.
