Discriminant Analysis - uibk.ac.at

Linear discriminant analysis (LDA), normal discriminant analysis (NDA), or discriminant function analysis is a generalization of Fisher's linear discriminant, a method used in statistics and other fields, to find a linear combination of features that characterizes or separates two or more classes of objects or events. The resulting combination may be used as a linear classifier, or, more commonly, for dimensionality reduction before later classification.

WebFisher discriminant method consists of ﬁnding a direction d such that µ1(d) −µ2(d) is maximal, and s(X1)2 d +s(X1)2 d is minimal. This is obtained by choosing d to be an eigenvector of the matrix S−1 w Sb: classes will be well separated. Prof. Dan A.
