二阶环形间隔分类器

A Two-Norm Annular Margin Classifier

采用二阶损失函数,提出了一种二阶环形间隔分类器,它运用超球面将两类训练样本隔开,同时最大化两类间隔.实验结果表明,不管是对平衡问题还是不平衡问题,所提出的二阶环形间隔分类方法都获得了比较好的分类效果.

A two-norm annular margin classifier is put forward based on two-norm cost function.The classifier defines a margin between two categories of training data with super sphere-structure and maximizes the margin.Experiment shows that the two-norm annular margin classifier improves the effects of classification for both balance and non-balance problems.
