Abstract

We proceed with the current comprehension of asymptotic properties of multiclass support vector machine (MSVM) in high-dimensional, low-sample-size (HDLSS) settings. We show that MSVM is biased under HDLSS settings and point out inconsistency problems for MSVM. We propose a bias-corrected MSVM (BC-MSVM) which works well even for HDLSS data set. We give simulation studies and discuss the performance of the BC-MSVM. Finally, we evaluate the performance of the BC-MSVM using microarray data set.
