An adaptive error penalization method for training an efficient and generalized SVM
A novel training method has been proposed for increasing efficiency and generalization of support vector machine (SVM). The efficiency of SVM in classification is directly determined by the number of the support vectors used, which is often huge in the complicated classification problem in order to represent a highly convoluted separation hypersurface for better nonlinear classification. However, the separation hypersurface of SVM might be unnecessarily over-convoluted around extreme outliers, as these outliers can easily dominate the objective function of SVM. This situation eventually affects the efficiency and generalization of SVM in classifying unseen testing samples. To avoid this problem, we propose a novel objective function for SVM, i.e., an adaptive penalty term is designed to suppress the effects of extreme outliers, thus simplifying the separation hypersurface and increasing the classification efficiency. Since maximization of the margin distance of hypersurface is no long...
