An easy way to … 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.
