Abstract: The goal of this comment is to first point out two loopholes in the paper by Li (2006): (1) so-designed efficient maximal margin criterion (MMC) algorithm for small sample size (SSS) problem is problematic and (2) the discussion on the equivalence with the null-space-based methods in SSS problem does not hold. Then, we will present a really efficient MMC algorithm for SSS problem.
