Efficient Algorithms for Personalized PageRank
We present new, more efficient algorithms for estimating random walk scores such as Personalized PageRank from a given source node to one or several target nodes. These scores are useful for personalized search and recommendations on networks including social networks, user-item networks, and the web. Past work has proposed using Monte Carlo or using linear algebra to estimate scores from a sin...
متن کاملCommunity Detection Using Time-Dependent Personalized PageRank
Local graph diffusions have proven to be valuable tools for solving various graph clustering problems. As such, there has been much interest recently in efficient local algorithms for computing them. We present an efficient local algorithm for approximating a graph diffusion that generalizes both the celebrated personalized PageRank and its recent competitor/companion the heat kernel. Our algor...
متن کاملEfficient Personalized PageRank Estimation for Many Sources and Many Targets
Personalized PageRank (PPR) is a measure of the importance of a node in a graph from the perspective of another node (we call these nodes the target and the source, respectively). PPR has been used in many applications, such as offering a Twitter user (the source) personalized recommendations of who to follow (targets deemed important by PPR). Computing PPR at scale is infeasible for networks l...
متن کاملPersonalized PageRank Solution Paths
Personalized PageRank vectors used for many community detection and graph diffusion problems have a subtle dependence on a parameter epsilon that controls their accuracy. This parameter governs the sparsity of the solution and can be interpreted as a regularization parameter. We study algorithms to estimate the solution path as a function of the sparsity and propose two methods for this task. T...
متن کاملFast Incremental and Personalized PageRank
In this paper, we analyze the efficiency of Monte Carlo methods for incremental computation of PageRank, personalized PageRank, and similar random walk based methods (with focus on SALSA), on large-scale dynamically evolving social networks. We assume that the graph of friendships is stored in distributed shared memory, as is the case for large social networks such as Twitter. For global PageRa...
