Small sphere large margin
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.

WebWe present a small sphere and large margin approach for novelty detection problems, where the majority of training data are normal examples. In addition, the training data also contain a small number of abnormal examples or outliers. The basic idea is to construct a hypersphere that contains most of the normal examples, such that the volume of this … WebJan 1, 2024 · In this paper, we have put forward maximal margin hyper-spheres SVM (MMHS-SVM). Our proposed MMHS-SVM simultaneously determines a pair of hyper-spheres by a single optimization, in which each one contains as many samples as possible and the centers keep away from each other to some extent.

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. the outer worlds han soloWebSmall sphere and large margin support vector machine (SSLM) is an effective method for imbalanced data classification. However, the hinge loss used in SSLM easily leads to sensitivity to the noises and thus yields poor generalization performance since the outliers gain the largest penalties.
