Fig 9. Organization based on brain regions of interest (ROIs) of resting-state fMRI correlation dataset consisting of transformed correlation matrices for m subjects.

Each column corresponds to an instance (or subject) I_j and each subset of rows corresponds to the correlations for an ROI attribute (p sets). The notation ${\widehat{A}}_{ak}^{\left(j\right)}$ represents the r-to-z transformed correlation between attributes (ROIs) a and k ≠ a for instance j.
