WebMore details can be found in [5]. Among these LDA extensions, PCA+LDA has received a lot of attention, especially for face recognition [1]. In this two-stage algorithm, an interme-diate dimension reduction stage using PCA is applied before LDA. The common aspect of previous LDA extensions is the computation of eigen-decomposition of certain ... WebLinear discriminant analysis (LDA) is particularly popular because it is both a classifier and a dimensionality reduction technique. Quadratic discriminant analysis (QDA) is a variant of LDA that allows for non-linear separation of data. Finally, regularized discriminant analysis (RDA) is a compromise between LDA and QDA.
