Independent Component Analysis Via Distance Covariance

National Science Foundation 2014 June 3. This paper introduces a novel statistical framework for independent component analysis ICA of multivariate data.

Independent Component Analysis Overview

Although many ICA methods have been developed they have received relatively little attention in the statistics literature especially in terms of rigorous theoretical investigation for statistical inference.

Current ICA approaches have focused on developing efficient algorithms under specific ICA models such as instantaneous or convolutive mixing conditions intrinsically assuming temporal independence or autocorrelation of the sources. Variation between groups and within groups and it maximizes the former.
