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 … WebFisher's Optimization Criterion Although Fisher did not derive his method of reducing dimensions in the same manner described above, these two methods can be shown identical. Fisher's idea was that if we wanted to find one direction, good classification should be obtained based on the projected data.
