Nonlinear prediction of chaotic time series

2019-12-09 07:27

chaotic time series usually puts a limit on the accuracy since the nonlinear predictor is basically an approximation of the unknown nonlinear mapping. In this paper, we propose using fusion of predictors as a method to improve the performance of chaotic time series prediction. Different nonlinear predictors with distinct characteristics includingNonlinear dependence of the level of a series on previous data points is of interest, partly because of the possibility of producing a chaotic time series. However, more importantly, empirical investigations can indicate the advantage of using predictions derived from nonlinear models, over those from linear models, as for example in nonlinear prediction of chaotic time series

Considerable progress has been made in recent years in the analysis of time series arising from chaotic systems. In particular, a variety of schemes for the shortterm prediction of such time series has been developed. However, hitherto all such algorithms have used batch processing and have not

Nonlinear Prediction of Chaotic Time Series, Physica D 35, Article in Physica D Nonlinear Phenomena 35(3): May 1989 with 151 Reads DOI: Nonlinear prediction of chaotic time series using support vector machines Abstract: A novel method for regression has been recently proposed by Vapnik et al. (1995, 1996). The technique, called support vector machine (SVM), is very well founded from the mathematical point of view and seems to provide a new insight in function approximation.nonlinear prediction of chaotic time series series) and the output of a system fed by the same time series (Figure 1a). Basically the prediction of the future is obtained by weighting appropriately the information contained in the recent past of the signal. The use of nonlinear models opens the door to study prediction of chaotic time series.

Time series modeling and prediction has been an active area of research due to the wide variety of applications in the nancial market, weather, biology, etc. The initial approaches typically relied on AR, MA, or ARMA univariate models. More sophisticated approaches rely on nonlinear modeling [6 and state space projection of the time series [18.
