Fisher classifier
WebAs a follow-up to my previous question, I want to use Fisher's classification method (I mean, projection method) to project the data given the fact that the two classes are normally distributed.How to approximate … 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.

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 WebImage recognition using this algorithm is based on reduction of face space domentions using PCA method and then applying LDA method also known as Fisher Linear Discriminant (FDL) method to obtain characteristic …
