A Statistical Analysis of Support Vector Machines of Forgetting Factor

Abstract (in Japanese) (See Japanese page) 
(in English) Support Vector Machines (SVMs) are, in general, trained in batch but any trick is necessary when the target to be trained is time-varying. In this study, we introduced the idea of forgetting factor (FF) of the RLS algorithm for adaptive filters and analyzed its effect on the SVM performance. More concretely, we derived the average generalization error of the algorithm in a simple case where input space is one-dimensional. The average generalization error of the SVMs with FF does not converge to zero, differently from the SVM in batch or online. We confirmed our results by computer simulations.
