Review of support vector machines for outliers

To improve the performance of the support vector machine (SVM) to the presence of outlier samples, the robust approaches based on SVM are studied. First, the internal reason why the generalization performance of SVM is deteriorated by outliers is analyzed. Then the current research trends and the latest developments of SVM on detecting and suppressing outliers are reviewed, which introduce the basic ideas of the approaches and their major characteristics. The aim of the paper is to sum up the studies on out...
