A Robust Approach for ICA with High-level Noisy Measurements and Unknown Number of Sources
This paper presents a robust approach for ICA based on the subspace method and parameterized t-distribution density model. This approach includes several techniques; pre-whitenmg with noise reduction, optimal dimensionality reduction (estimation of unknow source number), and the decomposition of the mixtures of sub-Gaussian and superGaussian source components. The results illustrate that the effectiveness of this robust approach.
