In this paper, we consider asymptotic properties of support vector machine (SVM) in high-dimension, low-sample-size (HDLSS) settings. In particular, we investigate the behavior of soft-margin SVM for the regularization parameterC. We show that SVM cannot handle imbalanced classification and SVM is very biased in HDLSS settings. In order to overcome such difficulties, we propose a robust SVM (RSVM). We show that RSVM gives preferable performances in HDLSS settings. Finally, we check the performance of RSVM in actual data analyses.
