WebLinear Discriminant Analysis (LDA) or Fischer Discriminants (Duda et al., 2001) is a common technique used for dimensionality reduction and classification. LDA provides class separability by drawing a decision region between the different classes. LDA tries to maximize the ratio of the between-class variance and the within-class variance.

Web2 Answers. The discriminant axis (the onto which the points are projected on your Figure 1) is given by the first eigenvector of W − 1 B. In case of only two classes this eigenvector is proportional to W − 1 ( m 1 − m 2), where m i are class centroids. Normalize this vector (or the obtained eigenvector) to get the unit axis vector v.
