Mixing time of PageRank surfers on sparse random digraphs

نویسندگان

چکیده

We consider the generalised PageRank walk on a digraph $G$, with refresh probability $\alpha$ and resampling distribution $\lambda$. analyse convergence to stationarity when $G$ is large sparse random given degree sequences, in limit of vanishing $\alpha$. identify three scenarios: much smaller than inverse mixing time relaxation equilibrium dominated by simple displays cutoff behaviour; larger contrary one has pure exponential decay rate $\alpha$; comparable there mixed behaviour interpolating between decay. This trichotomy shown hold uniformly starting point

Longest cycles in sparse random digraphs

Long paths and cycles in sparse random graphs and digraphs were studied intensively in the 1980’s. It was finally shown by Frieze in 1986 that the random graph G(n, p) with p = c/n has a cycle on at all but at most (1 + ε)ce−cn vertices with high probability, where ε = ε(c) → 0 as c → ∞. This estimate on the number of uncovered vertices is essentially tight due to vertices of degree 1. However,...

Using Polynomial Chaos to Compute the Influence of Multiple Random Surfers in the PageRank Model

The PageRank equation computes the importance of pages in a web graph relative to a single random surfer with a constant teleportation coefficient. To be globally relevant, the teleportation coefficient should account for the influence of all users. Therefore, we correct the PageRank formulation by modeling the teleportation coefficient as a random variable distributed according to user behavio...

PageRank and random walks on graphs

We examine the relationship between PageRank and several invariants occurring in the study of random walks and electrical networks. We consider a generalized version of hitting time and effective resistance with an additional parameter which controls the ‘speed’ of diffusion. We will establish their connection with PageRank . Through these connections, a combinatorial interpretation of PageRank...

Random Alpha PageRank

We suggest a revision to the PageRank random surfer model that considers the influence of a population of random surfers on the PageRank vector. In the revised model, each member of the population has its own teleportation parameter chosen from a probability distribution, and consequently, the ranking vector is random. We propose three algorithms for computing the statistics of the random ranki...
