用于不平衡数据分类的模糊支持向量机算法
A fuzzy support vector machine algorithm for imbalanced data classification
摘要
Abstract
As an effective machine learning technique,support vector machine (SVM)has been successfully applied to various fields.However,when it comes to imbalanced datasets,SVM produces suboptimal classification models.On the other hand,the SVM algorithm is very sensitive to noise and outliers present in the datasets.To overcome the disadvantages of imbalanced and noisy training datasets,a novel fuzzy SVM algorithm for imbalanced data classification is proposed.When designing the fuzzy membership function,the proposed algorithm takes into account not only the distance between the training sample and its class center,but also the tightness around the training sample. Experimental results show that the proposed fuzzy SVM algorithm can effectively handle the imbalanced and noisy problem.关键词
