A Fast Fixed-Point Algorithm Based on ICA
Wei Guo · Audio Engineering · 2007
The fundamental problems of ICA(Independent Component Analysis) about the model definition and mathematical principles are given. Based on analysis of the existing algorithms, the FastICA is introduced. The convergence speed of FastICA is fast and the times of iterations is reduced from about 2 000 to 3~10 using FastICA. Finally, the experimental results show that the FastICA has good performance for blind source separation and robustness.
