Figure 5

In circles is shown the evolution of normalised mutual information, NMI, between communities found in the original network prior aggregation, and communities found in aggregated networks at several square sizes, and lifted back to the original network (as explained in Methods). In squares, the evolution of the aggregability index, η, between communities and aggregating partitions at the finest level compared with the same sizes as before. For the Twitter dataset (in blue) the initial level corresponds to users centroids and the timescale is kept to \(\rho =1\). For the mobile phone dataset (in pink), the initial level corresponds to towers. The timescale ρ was kept constant with a value of 0.75
