Independent Component Analysis using a Geometric Approach
For the problem of independent component analysis we propose an alternative solution to determining independent sources from channels using a geometric approach. The resulting algorithm inherits many properties of the then applicable simplex algorithm, namely computational tractability even in high dimensions (), and yields demixing estimates comparable to standard algorithms (e.g. FastICA) for extremely small sample sizes (). Our results are corroborated by demixing of a real world ECG data set from the PhysioNet database
