Mean Field Analysis of Personalized PageRank with Implications for Local Graph Clustering

Konstantin Avrachenkov, Arun Kadavankandy, Nelly Litvak

摘要:

我们分析了个性化PageRank的平均场模型的Erdos-Renyi随机图包含一个密集种植Erdos-Renyi子图。我们调查的制度,个性化PageRank的值集中在平均场值。我们还研究了个性化PageRank中唯一的参数阻尼因子的优化。我们的理论研究结果有助于理解个性化PageRank的适用性及其局限性的局部图聚类。

英文摘要:

We analyse a mean-field model of Personalized PageRank on the Erdos-Renyi random graph containing a denser planted Erdos-Renyi subgraph. We investigate the regimes where the values of Personalized PageRank concentrate around the mean-field value. We also study the optimization of the damping factor, the only parameter in Personalized PageRank. Our theoretical results help to understand the applicability of Personalized PageRank and its limitations for local graph clustering.
