A Small Sphere and Large Margin Approach for Novelty Detection …

WebD. Small Sphere Large Margin (SSLM) (3) Recently in [16], authors combine the ideas of one-class SVM and conventional binary SVM to propose SSLM model. This model is to minimize the hypersphere containing all normal data and simultaneously maximize the margin, distance from outliers to the optimal hypersphere. WebJan 1, 2024 · Xu (2016) proposed a maximum margin of twin spheres support vector machine (MMTSSVM). MMTSSVM constructs two homocentric hyper-spheres rather than two different hyper-spheres. Namely, the small sphere contains as many positive samples as possible, and most negative samples are pushed outside the large sphere. devyne brown
