Speed up ICA algorithm without loss of quality using DR-LCO algorithm
We introduce a new algorithm to speed up the ICA algorithm for blind source separation. In this technique, oscillations of the learning curve are first detected and then removed. This leads to making use of a larger step-size parameter and thus a faster ICA. Simulations results show that in average the proposed DR-LCO algorithm is at least three times faster than the ICA, while the quality of separated signals becomes even better.
