For detailed description of linear discriminant analysis and MATLAB source code, easy to use.
Linear discriminant analysis (Linear Discriminant Analysis, LDA), also known as the Fisher linear discriminant(Fisher Linear Discriminant, FLD), is the classic algorithm of pattern recognition, it was in the year 1996 by Belhumeur
Introduction of pattern recognition and artificial intelligence. Sexual discriminant analysis of the basic thought is the higher-dimensional projection mode samples to the best
Vector space in order to extract classified information and the effect of the compression feature space dimension, guarantee mode samples after projections in the new
Subspace of minimum and maximum distances between clusters from within a class, namely model separability in that space has the best. Therefore,
It is an effective method of feature extraction. Using this method can make the projection mode samples class after scattering matrix the
