基于差分进化的BP神经网络预测混沌时间序列
Prediction for chaotic time series of BP neural network based on differential evolution
摘要
Abstract
A prediction method for chaotic time series of BP neural based on DE is proposed to overcome the problems such as long computing time and easy to fall into local minimum by incorporating Differential Evolution(DE)and neural network. DE is used to optimize the weights and thresholds of BP neural network, and the BP neural network is used to search for the optimal solution. The efficiency of the proposed prediction method is tested by the simulation of three typical nonlinear systems, and the precision of this algorithm is compared with BP algorithms. The simulation results show that the proposed method has better nonlinear fitting ability and higher forecasting accuracy.关键词
