A Complete Characterization of a Family of Solutions to a Generalized Fisher Criterion
Marco Loog; 8(72):2121−2123, 2007.
Recently, Ye (2005) suggested yet another optimization criterion for discriminant analysis and proposed a characterization of the family of solutions to this objective. The characterization, however, merely describes a part of the full solution set, that is, it is not complete and therefore not at all a characterization. This correspondence first gives the correct characterization and afterwards compares it to Ye's.
