Fisher’s Linear Discriminant: Intuitively Explained

WebFisher discriminant method consists of finding a direction d such that µ1(d) −µ2(d) is maximal, and s(X1)2 d +s(X1)2 d is minimal. This is obtained by choosing d to be an eigenvector of the matrix S−1 w Sb: classes will be well separated. Prof. Dan A.
