Huagang Yu, Gaoming Huang, Jun Gao · International Journal of Computer Network and Information Security · 2010
To solve the problem of nonlinear blind source separation (BSS), a novel algorithm based on kernel multiset canonical correlation analysis (MCCA) is presented.Combining complementary research fields of kernel feature spaces and BSS using MCCA, the proposed approach yields a highly efficient and elegant algorithm for nonlinear BSS with invertible nonlinearity.The algorithm works as follows: First, the input data is mapped to a high-dimensional feature space and perform dimension reduction to extract the effective reduced feature space, translate the nonlinear problem in the input space to a linear problem in reduced feature space.In the second step, the MCCA algorithm was used to obtain the original signals.
