There are two broad classes of methods for determining the parameters of a linear classifier . They can be generative and discriminative models. Methods of the former model joint probability distribution, whereas methods of the latter model conditional density functions . Examples of such algorithms include: • Linear Discriminant Analysis (LDA)—assumes Gaussian conditional density models WebThermo Scientific instruments, equipment, software, services and consumables empower scientists to solve for complex analytical challenges in pharmaceutical, biotechnology, …

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. WebThe fisher linear classifier for two classes is a classifier with this discriminant function: h ( x) = V T X + v 0. where.
