Fisher matrix analysis

WebLet's start with finding one direction which maximizes this ratio. And we will assume the within-class covariance matrix of X is W, i.e., the common covariance matrix of the classes (computed by LDA). Then we would also need a between-class covariance matrix denoted by B. This is the covariance matrix you compute using only the mean vectors. Webencountered in speech analysis, the asymptotic Fisher infor-mation J1 must be modified to yield accurate CRB values for LP coefficients. Exact computations of the CRB can be derived from the exact Fisher information matrix J M accord-ing to the following equation (Friedlander and Porat, 1989): J M ¼ J ^þð1 p=MÞJ1; (8)
