| Abstract(in English) | In this paper, a multiclass classification method is presented. To classify multiple classes, we combine two-class classifiers of all pair of classes. To combine two-class classifiers, we propose a Resemblance Model to calculate a posteriori probability. We showed the validity of this model by using approximation of a posteriori probability formula. When we have a posteriori probability, we can apply the Bayes classification rule to obtain the optimal decision, and furthermore, control the rejection quite easy. As an example, we performed a experiment of handwritten numerals recognition and obtained the good result. |
