Linear Discriminant Analysis Supervised method that maximizes separation between classes and minimizes variance within classes for a labeled dataset Compute the mean and variance of each independent variable for every class C i 2.Calculate the within-class (˙ 2 w) and between-class (˙ b) variance 3.Find the matrix W= (˙2 w) 1(˙2 b) that ...

analysis is also called Fisher linear discriminant analysis after Fisher, 1936; computationally all of these approaches are analogous). If we code the two groups in the analysis as 1 and 2 , and use that variable as the dependent variable in a multiple regression analysis, then we would get results that are analogous to those we would obtain ...

Linear Discriminant Analysis Notation I The prior probability of class k is π k, P K k=1 π k = 1. I π k is usually estimated simply by empirical frequencies of the training set ˆπ k = # samples in class k Total # of samples I The class-conditional density of X in class G = k is f k(x). I Compute the posterior probability Pr(G = k | X = x) = f k(x)π k P K l=1 f l(x)π l I By MAP (the ...
