Abstract

The selection of hyper-parameters is a crucial challenge in Support Vector Machine modeling. Differed from using basic statistics of residuals in previous method, the new approach selects hyper-parameters by checking whether or not there is information redundancy in residual sequence. Furthermore, Omni-Directional Correlation Function (ODCF) is applied to test redundancy in residual, and the proof of the accuracy of the methodology is given in terms of numerical demonstration. Experiments conducted on benchmark time series, annual sunspot number and Mackey-Glass time series; indicate that the proposed method has better performance than the recorded in previous literatures.
