We study the problem of differentially private constrained maximization of decomposable submodular functions. A submodular function is decomposable if it takes the form of a sum of submodular functions. The special case of maximizing a monotone, decomposable submodular function under cardinality constraints is known as the Combinatorial Public Projects (CPP) problem [Papadimitriou et al., 2008]. Previous work by Gupta et al. [2010] gave a differentially private algorithm for the CPP problem. We… Expand

Differentially Private Monotone Submodular Maximization Under Matroid and Knapsack Constraints

A differentially private (1− κe )-approximation algorithm is proposed, where κ ∈ [0, 1] is the total curvature of the submodular set function, which improves upon prior works in terms of approximation guarantee and query complexity under the same privacy budget. Expand

This work focuses on the question of maximizing a monotone submodular function under a cardinality constraint when given access to a noisy oracle of the function, and shows that no randomized algorithm can obtain an approximation ratio better than 1/2+o(1) and no non-trivial approximation guarantee can be obtained.
