    Contrast Functions for Independent Subspace Analysis

    We consider the Independent Subspace Analysis problem from the point of view of contrast functions, showing that contrast functions are able to partially solve the ISA problem. That is, basic ICA can solve the...

    Strong Sub- and Super-Gaussianity

    We introduce the terms strong sub- and super-Gaussianity to refer to the previously introduced class of densities log-concave is x 2 and log-convex in x 2 respectively. We derive r...

    Super-Gaussian Mixture Source Model for ICA

    We propose an extension of the mixture of factor (or independent component) analyzers model to include strongly super-gaussian mixture source densities. This allows greater economy in representation of densiti...
