Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents a new method for learning kernel classifiers. First, we formulate a novel learning scheme called ``General Loss Minimization (GLM).'' The formulation is based on Bayes decision theory which can handle various losses as well as prior probabilities. Then, we propose a new learning method for kernel classifiers derived from GLM. We also show that support vector machines (SVM) can be derived from GLM as a special case. The derivation clarifies some interesting similarities and differences between SVM and the proposed method. Finally, we confirm effectiveness of the proposed method in expriments with artificial and real databases. The exprimental results show that the proposed method achieves almost the same or better accuracy than SVM in spite of stronger sparsity of classifier parameters.
