Extended cosine measure has been proposed as one of the method of metric learning which learns metric matrix
expressing the characteristics of training data.
However, this method introduces a unique metric matrix and estimate it by learning of all training data.
Therefore, there is a room to improve this method because document data has normally different statistical characteristics
in each category. In this study, we propose the way of learning metric matrices for each category.
To show the effectiveness of our proposed method, simulation experiment is conducted. |
