On the configuration of learning parameter to enhance convergence speed of back propagation neural network

역전파 신경회로망의 수렴속도 개선을 위한 학습파라메타 설정에 관한 연구

In this paper, the method for improving the speed of convergence and learning rate of back propagation algorithms is proposed which update the learning rate parameter and momentum term for each weight by generated error, changely the output layer of neural network generates a high value in the case that output value is far from the desired values, and genrates a low value in the opposite case this method decreases the iteration number and is able to learning effectively. The effectiveness of proposed method is verified through the simulation of X-OR and 3-parity problem.
