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 ... WebSep 21, 2024 · Linear Fisher markets are a fundamental economic model with diverse applications.
