Top-9 connections (pair of ROIs) of the three ground truth matrices and three embedding similarity matrices in Fig. 2. In each subfigure, we used the dotted frame of the same color to represent the same connections. The involved region labels are listed below the subfigure and marked by the dots of the same color with the dotted frame. Within each block, the connections are arranged by their rank following the order from top to bottom and left to right. The connections without the dotted frame represent they are only found in either ground truth matrices or embedding similarity matrices, and their labels are mark by black.
