ML-Based MMSE Source Separation

Simplified geometrical visualization of the optimality-gap between the estimation errors of the MMSE and the ML-based MMSE estimates.

This package contains three files: a (readme) detailed instruction file, the main function for the ML-based MMSE separation, and a script which demonstrates this function’s operation for an ICA problem with temporally-diverse stationary Gaussian sources.
