WebMar 28, 2008 · Fisher's linear discriminant is a classification method that projects high-dimensional data onto a line and performs classification in this one-dimensional space. The projection maximizes the distance … 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. That is, αGF, for any α 6= 0 is also a solution to FLDA. 3 ...
