Fisher linear discriminant analysis fld

WebLinear discriminant analysis (LDA; sometimes also called Fisher's linear discriminant) is a linear classifier that projects a p -dimensional feature vector onto a hyperplane that divides the space into two half-spaces ( Duda et al., 2000 ). Each half-space represents a class (+1 or −1). The decision boundary.
