| Abstract: | Because of the limitation of traditional BP neural network models(NNM),their convergence speed is generally slow.This paper is to modify and improve the BP NNMs,in order to enhance their convergence speed.The improved BP NNM is used to predict the historical export volumes of Xiamen Port and it is found that it has a very good accuracy through comparison of the simulation results and actual results.The prediction results show that the proposed model reduces the time required for the convergence and enhances... |
