基于迟滞神经网络的商品零售价格指数预测
Prediction of commodity retail price index based on hysteretic neural network
摘要
Abstract
Hysteretic characteristic is brought into neural network, and hysteretic neural network is constructed by changing activation function into hysteretic function. Hysteretic characteristic can enhance the inertia of keeping original state, which can reduce the error rate of state alteration, and enhance the storage and memory ability. Switching characteristic of hysteretic segment response can restrain fault saturation phenomenon during the training. A hysteretic neural network with the structure and training algorithm of feed-forward neural network is proposed to predict the time series. It is applied to predict the commodity retail price index. Prediction results show that the network has good capacity of generalization, and its forecast validity is better than that of conventional neural network.关键词
