WebFor the linear combination Z, the between-class variance is a T Ba and the within-class variance is a T Wa. Fisher’s optimization becomes. To solve the above maximization, let eigen-decomposition of W = V W D W V T W. Let W = (W ½) T W ½, where W ½ = D ½ W V T W. Define b = W ½ a, then a = W-½ b. The optimization becomes. Define B* = (W ... WebFisher’s Linear Discriminant Analysis (LDA) Principle: Use label information to build a good projector, i.e., one that can ‘discriminate’ well between classes ä Define“between …
