| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Selecting relevant features is a fundamental task in machine learning. Although many approaches have been investigated so far, regularized-learning with sparsity-inducing norms, such as LASSO, would be one of the most promising ones. In this paper, we investigate a challenging problem beyond feature selection --- feature-set enumeration, where we try to enumerate all $\epsilon$-optimal feature-sets in the $l_0$-regularized feature selection with submodular measures. We develop a novel algorithm for this problem based on the branch-and-bound framework, where bounding and cutting are performed using the structure of binary decision diagrams (BDDs) and the submodularity of selection measures. The performance of the proposed algorithm is investigated through experiments with artificial datasets. | |
