Random walk centrality for temporal networks
Webb11 apr. 2024 · PageRank is an algorithm that produces a walk-based metric for node centrality given a directed network 6,38. The obtained centrality values approximate the probability of finding a random walker ... Webb15 apr. 2024 · Spreading dynamics on a large network. In figure 1 (a) we plot the fraction of infected nodes at time t obtained, for infectivity λ = 0.5, in a temporal network with N = 1000 nodes produced by a DARN ( p) model with y = 0.002 and q = 0.9. This is compared to the case of a temporal network without memory, generated by setting q = 0 in our model.
