Foundations of Independent Component Analysis detailed in new arXiv paper

This paper delves into the mathematical underpinnings of linear independent component analysis (ICA), targeting readers with a background in measure-theoretic probability theory. It details the theory of characteristic functions for probability measures and explores identifiability results for ICA models under progressively stricter assumptions on the sources. The work also introduces an online equivariant gradient descent algorithm for recovering independent sources in a standard noiseless, non-Gaussian ICA scenario. AI
