On the Equivalence of Linear Dimensionality-Reducing Transformations

Marco Loog; 9(Nov):2489--2490, 2008.

Abstract

In this JMLR volume, Ye (2008) demonstrates the essential equivalence of two sets of solutions to a generalized Fisher criterion used for linear dimensionality reduction (see Ye, 2005; Loog, 2007). Here, I point out the basic flaw in this new contribution.
