Guaranteed Non-convex Optimization: Submodular Maximization over Continuous Domains

AISTATS 2017poster

Submodular continuous functions are a category of (generally) non-convex/non-concave functions with a wide spectrum of applications. We characterize these functions and demonstrate that they can be maximized efficiently with approximation guarantees. Specifically, i) We introduce the weak DR proper…

Guarantees for Greedy Maximization of Non-submodular Functions with Applications

ICML 2017poster

We investigate the performance of the standard Greedy algorithm for cardinality constrained maximization of non-submodular nondecreasing set functions. While there are strong theoretical guarantees on the performance of Greedy for maximizing submodular functions, there are few guarantees for non-sub…
