Fig. 2.
Left panel: 100×100 dimensional adjacency matrix 𝒜 that represents assumed connectivity between 100 nodes (variables). Adjacency matrix entries colored with red are equal 1 and denote common assigment of the two nodes to one of the five connectivity modules. Adjacency matrix entries colored with white are equal 0 and denote that the two nodes are not connected with each other. Right panel: corresponding normalized Laplacian matrix.
