We study outlier detection and robust learning problem for support vector machine (SVM). In the literature there are two main approaches to this problem. The first one is called direct approach in which outliers are directly identified and their influences are reduced in the training process, while the other is called indirect approach in which the loss function is modified to be robust to outliers. In this paper, we introduce a new algorithm for this problem using parametric programming technique. The algorithm enables us to trace the path of the SVM solutions when the loss incurred to the most influential instance is continuously decreased. A simple numerical experiment is conducted to illustrate the behavior of the algorithm and its connections with direct and indirect approaches are discussed. |
