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.

WebOct 5, 2015 · Then for any observed vector x and class conditional densities f 1 ( x) and f 2 ( x) the Bayes rule will classify x as belonging to group 1 if f 1 ( x) ≥ f 2 ( x) and as class 2 otherwise. The Bayes rule turns out to be a linear discriminant classifier if f 1 and f 2 are both multivariate normal densities with the same covariance matrix.

WebThe original LDA formulation, known as the Fisher linear Discriminant Analysis (FLDA)(5) deals with binary-class classification. The key idea in (FLDA) is to look for a direction that separates the class mean well (when projected onto that direction) while achieving a small variance around these means. FLDA bears strong connections to linear
