Fisher linear
WebFisher’s linear discriminant finds out a linear combination of features that can be used to discriminate between the target variable classes. In Fisher’s LDA, we take the separation by the ratio of the variance between the classes to the variance within the classes. To understand it in a different way, it is the interclass variance to ... WebThe fisher linear classifier for two classes is a classifier with this discriminant function: h ( x) = V T X + v 0. where. V = [ 1 2 Σ 1 + 1 2 Σ 2] − 1 ( M 2 − M 1) and M 1, M 2 are means and Σ 1, Σ 2 are covariances of the classes. V can be calculated easily but the fisher criterion cannot give us the optimum v 0.
