| Abstract: | For improving the decision speed of one-class SVDD, a fast decision approach is proposed in this paper, called FDA-SVDD, by utilizing the preimage in original feature space corresponding to the center of sphere in kernel feature space, by which the decision complexity of SVDD is reduced from O(n) to O(1). Meanwhile, two approximate algorithms for finding preimage are presented based on analyzing its position in the original space. Experimental results on extensive datasets show that the proposed method can ... |
