基于粒子滤波的混沌时间序列局域多步预测
Particle filtering based local multi-step prediction for chaotic time series
摘要
Abstract
It has important value and practicability(such as stock forecasting,rainfall forecasting and temperature fore-casting)to predict the chaotic time series. It is difficult to predict the chaotic time series due to its uncertainty and realization of multi-step prediction. The least square method is used to solve the model parameters and perform local prediction for the chaotic time series,but has low prediction accuracy. In order to improve the accuracy of local linear prediction,a local multi-step pre-diction method based on particle filtering(PF)is proposed for chaotic time series. The particle filtering is adopted to optimize the parameters to obtain more accurate optimization model for multi-step prediction. Simulation results show that the multi-step and single-step prediction effects of this method are improved significantly.关键词
