Weighted LeaderRank


Weighted LeaderRank is a variant to LeaderRank via assigning degree-dependent weights onto links associated with the ground node.
If network is described by an (N+1)-dimensional weighted adjacency matrix W, so: (i) if aij = 0, then wij = 0; (ii) for any normal node i and the ground node g, wgi = (kini) and wig = 1, where is a free parameter; (iii) for all other cases, wij = 1. After determining the weight of every link, the dynamics follows a biased random walk, namely the score from node j to node i is proportional to the weight wji:

Same to LeaderRank, use final scores in the steady state to quantify nodes’ influences.
