Predictive Analysis in Complex Dynamic Networks

Abstract

Node attributes and links in information networks often evolve over time and are inextricably dependent on each other. In addition, the evolving network is partially observed, multiple kinds of links exist among nodes and various nodes have different temporal dynamics. In this talk we will present an overview of the results of our ongoing DARPA GRAPHS big data project aimed to address these challenges by developing a structured learning Gaussian conditional random field (GCRF) model, which is shown to be more accurate than several unstructured alternatives in forecasting dynamics of evolving complex networks.
