Reconstructing Mesoscale Network Structures

Figure 5

Evolution of the AIC and BIC values for the DIN across the quarters 1998Q1-2008Q4: while the SBM (blue trend) must be preferred to the traditional DRG (being the network composed by parts with different link densities), heterogeneous benchmarks are, generally speaking, to be preferred. Although the DCM wins in the vast majority of cases (both for the bow-tie and the core-periphery mesoscale structures), quarters exist where the DCM and the RCM compete; BIC, on the other hand, lets the SBM win sometimes, when analysing the DIN core-periphery structure. The ddc-SBM experiences convergence problems throughout the entire temporal period.
