fMRI experiment: (a) Task-related IC extracted by FastIca from a fMRI experiment where the subject performed a visual task while in the scanner. (b) Color-coded spatial activation pattern of this IC in an axial brain slice. (c) The rank of this IC according to CLRG and the comparison methods for varying dimensionality reduction. This interesting IC is always identified among the top-ranked components by CLRG.
