Abstract(in English) | In this paper, we propose a new optimization algorithm for multiple instance learning (MIL). MIL is a supervised learning paradigm in which supervised labels are only assigned to a set of instances called bags. MIL algorithms are usually formulated as non-convex optimization problems because the labels of instances are unknown. In this study, we propose a homotopy-based non-convex optimization algorithm for finding local optimal solutions of a well-known MIL algorithm called Multi-Instance SVM (MI-SVM). To this end, we introduce a parametric program (a family of parametrized optimization problems) which contains both of convex standard SVM and non-convex MI-SVM. Then, we propose an algorithm that can compute a path of solutions of the parametric program when the former standard SVM problem is gradually modified to the latter MI-SVM problem. We demonstrate the behavior of our proposed approach through simple experiments. |
