Submodular Optimization and Nonconvexity
Stefanie Jegelka

Fri Dec 09 04:30 AM -- 05:00 AM (PST) @

Despite analogies of submodularity and convexity, submodular optimization is closely connected with certain "nice" non-convex optimization problems for which theoretical guarantees are still possible. In this talk, I will review some of these connections and make them specific at the example of a challenging robust influence maximization problem, for which we obtain new, tractable formulations and algorithms.
