Comparison of the NMLE ICA algorithm with three other ICA approaches on two yeast cell cycle data (dataset 1 and 2), yeast stress data (dataset 3), and data (dataset 4). Eight different ICA algorithms and variations (Table ) were compared. The full comparison is shown in the web supplement. Overall, NMLE, ExtIM and FPsymth performed similarly except in the dataset 2. NICApoly performed comparably with NICAgauss. Both nonlinear approaches were better than NMLE in the two smaller datasets, but performed relatively poorly in the two larger datasets.
