Abstract (in Japanese) (See Japanese page) 
(in English) In this study, we examine the learning method of each category distribution under underdetermined environment that category information of few data are known. Because we use multimodal data distribution, learning for each category distribution is difficult. Therefore, by using the given category information, and projecting the data into low-dimensional subspace suitable for category classification, we propose a method to GMM approximation. Specifically, we consider each category distribution as a linear combination of subclasses of the multidimensional normal distribution, and determine the projection space by appropriate criteria. In the experiment, we compared the proposed method with the conventional method by changing the parameters. In some cases, the proposed method showed higher accuracy than the conventional method.
