AUC score comparison on brain datasets with ICA components by using all, top 5% and bottom 5% time-points only. We train and test a logistic regression (LR) model using the time-points identified by DICE and compare the results when using top and bottom 5% time-points. We see that using only top 5% time-points are enough to almost reach the AUC using all time-points.
