| Abstract(in English) | We propose a new method for selection of the number of components of a mixture model for pattern classifiers. In previous methods, the optimal number of components is selected independently for each class. When the main concern is classification and only a limited number of training samples is available, consideration of class-separability may be helpful. One selection criterion is based on a classification-oriented MDL(Minimum Description Length)principle. In this method, we evaluate each classifier by both the classification accuracy for the training samples and the complexity of the classifier itself. We select the optimal combination of the number of components by a trade-off between the two factors. The effectiveness of the proposed method was confirmed by experiments using artificial and real data. |
