| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Cost-sensitive learning is useful for binary classification when the costs of miss-classifications are not symmetric. In this report, we study the problem of selecting a common set of features when several binary classifiers with different costs are trained. To this end, we introduce mixed norm regularization framework and formulate the problem as a regularized empirical risk minimization. We also develop its regularization-path following algorithm, and show that the path of the optimal solutions has piecewise-constant form. A simple simulation study was conducted to illustrate the effectiveness of the presented approach. |
