The grant funds research to develop robust and scalable algorithms for learning hidden structures in sparse network data. The University of Southern California will conduct research to combine node-level side information with network interaction data to more effectively analyze network data and detect latent subpopulations. The research has three parts: devising clustering algorithms using semidefinite programming; improving algorithm robustness to adversarial perturbations; and developing low-computation implementations to scale algorithms to large network data. Findings will be applied across domains utilizing resulting clustering tools and statistical optimization methods. The grant supports graduate student training and provides tools to understand complex network systems, advancing the program's goals.
