[2] introduced SVC, a non-parametric clustering method. It is closely related to one-class classification and density estimation using SVMs as proposed in [22], [23], [24] where a set of contours enclose data points with similar underlying distributions. Ben-Hur et al. [2] interpret these contours as ...
