Weboriginal Fisher Linear Discriminant Analysis (FLDA) (Fisher, 1936), which deals with binary-class problems, i.e., k = 2. The optimal transformation, GF, of FLDA is of rank one and is given by (Duda et al., 2000) GF = S+ t (c (1) −c(2)). (6) Note that GF is invariant of scaling.

WebThe fisher linear classifier for two classes is a classifier with this discriminant function: h ( x) = V T X + v 0. where. V = [ 1 2 Σ 1 + 1 2 Σ 2] − 1 ( M 2 − M 1) and M 1, M 2 are means and Σ 1, Σ 2 are covariances of the classes. V can be calculated easily but the fisher criterion cannot give us the optimum v 0. http://www.cse.buffalo.edu/~jcorso/t/555pdf/impca.pdf
