| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this study, we propose new matrix factorization methods for multiple matrices. The research to analyze multiple data is gathering an attention of many researchers and multiple matrix factorization method with non-negativity constraint is one of its outcomes. It is shown that the strength of this method, high pattern extraction ability and interpretability, is effective even for large sparse matrices. This method, however, doesn't consider the scenario where relation between patterns of each dataset is not one to one. Therefore, we construct new matrix factorization models which can deal with those conditions. The two types of algorithms with parameter constraint and with no parameter constraint is derived. We confirmed the effectiveness of proposed methods with numerical experiment. |
