Spectral Coarse-Graining and Rescaling for Preserving Structural and Dynamical Properties in Graphs

M. Schmidt, F. Caccioli, T. Aste

We introduce a graph renormalization procedure based on the coarse-grained Laplacian, which generates reduced-complexity representations for characteristic scales identified throug…
