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.
