Fisher’s Linear Discriminant — Machine Learning from Scratch

WebLinear and quadratic discriminant analysis are the two varieties of a statistical technique known as discriminant analysis. #1 – Linear Discriminant Analysis Often known as LDA, is a supervised approach that attempts to predict the class of the Dependent Variable by utilizing the linear combination of the Independent Variables. WebFisher linear discriminant analysis (LDA), a widely-used technique for pattern classica-tion, nds a linear discriminant that yields optimal discrimination between two classes which can be identied with two random variables, say X and Y in Rn. For a (linear) discriminant characterized by w 2Rn, the degree of discrimination is measured by the WebFisher and Kernel Fisher Discriminant Analysis: Tutorial 2 of kernel FDA are facial recognition (kernel Fisherfaces) (Yang,2002;Liu et al.,2004) and palmprint recognition (Wang & Ruan,2006).
