Network Centrality as Statistical Inference in Large Networks
Massive data-sets are often generated by a large network of users. And large networks represent a fundamental medium for the spreading and diffusion of various information where the actions of certain users increase the susceptibility of other users to the same; this results in the successive spread of information from a small set of initial users to a much larger set. Examples include the spread of rumors in online social networks and power outage in smart grids. Modeling these massive data-sets as huge graphs, we introduce the idea of network centrality as statistical inference in large networks to solve two optimization problems, namely rooting out rumor sources and averting cascading failures. A network centrality with statistical basis accurately captures the optimality of the problems, and brings graph algorithm machinery to bear on solving the problems. We conclude the talk with insights on putting the theory into practice in graph analytics software development.
