Abstract: Based on traditional artificial neural network using Genetic Algorithm(GA),this paper introduces a further improved method applying two independent training sets to train the network in order to optimize the neural network structure.Aiming at the characteristics of neural network structure,a model using a hybrid GMDH and artificial neural network is established.It can make the selection of input-lay units easily and improve the ability of rate of studying and the adaptability of neural network.Finally a case implementing this model in analyzing and predicting the grain production of China is presented,and the result indicates that the combined model is an effective way to improve forecasting accuracy.
