In this paper, we generalize the efficient geometric ICA algorithm FastGeo to overcomplete settings with more sources than sensors. The solution to this underdetermined problem will be presented in a two step approach. With geometric ICA we get an efficient method for the step--matrix-recovery--while the second step--source-recovery-- uses a maximum-likelihood approach.
