A New PLS Method Suitable to Deal with the Discriminant Analysis Problems with Two Class Samples

Abstract

Abstract: Anew PLSmethod that is very suitable dealing with the discriminant analysis problems with two class samples has been developed.In this method the dependent function y has been transformed by use of the Sigmoid function, that is similar to the neural network algorithm.Therefore a new optimization criteria can be used to extract the latent variables t₁, t₂,...., in PLSmethod.The good classification graphics constructed by the latent variables, and the ideal direction vectors of discrimination can all be obtained.

Key words: PLS, Discriminant analysis, Neural network
