Some Notes on Blind Source Separation Using Generalized Eigenvalues

By analyzing the two algorithms proposed by Lucas Parra and Liu, this paper presents the relation between them. We first introduce these two related blind source separation algorithms, then present the relation between the two blind source separation algorithms which using generalized eigenvalues, finally gives out the conclusion that the algorithm proposed by Lucas Parra is a particular instance of those proposed by Liu, so the frame of the optimizing cost function of Liu is more of universality and applicability.
