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 … 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 ...

WebLDA is the direct extension of Fisher's idea on situation of any number of classes and uses matrix algebra devices (such as eigendecomposition) to compute it. So, the term "Fisher's Discriminant Analysis" can be seen as obsolete today. "Linear Discriminant analysis" should be used instead. See also.
