| Abstract(in English) | We propose a nonparametric multi-class classifier based on a family of spheres, each of which is the minimum covering sphere for a subset of positive samples and does not contain any negative samples. We first reformulate the subclass method originally defined for axis-parallel rectangles. According to our new framework, we introduce an exact algorithm and an efficient incremental randomized algorithm to construct a subclass family. In addition, we propose the soft-classification version of subclass method and evaluate these algorithms by some numerical experiments. |
