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. WebJun 6, 2016 · In this paper, we introduce a hybrid architecture which combines Fisher …

WebThe model fits a Gaussian density to each class, assuming that all classes share the same covariance matrix. The fitted model can also be used to reduce the dimensionality of the input by projecting it to the most discriminative directions, using the transform method.
