Independent Component Analysis (ICA) is a challenging problem in the areas of statistical signal processing and unsupervised machine learning. This talk studies the problem of linear ICA .

Recently, there has been an increasing interest in using geometric optimisation methods to solve linear ICA problems. Two prominent classes of geometric linear ICA methods, Newton-type methods and Jacobi-type methods, will be discussed. This talk will mainly focus on the development and convergence analysis of the proposed geometric linear ICA methods, both theoretically and numerically.
