Risk-Sensitive Submodular Optimization
The conditional value at risk (CVaR) is a popular risk measure which enables risk-averse decision making under uncertainty. We consider maximizing the CVaR of a continuous submodular function, an extension of submodular set functions to a continuous ...

Interactive submodular set cover
We introduce a natural generalization of submodular set cover and exact active learning with a finite hypothesis class (query learning). We call this new problem interactive submodular set cover.

Online submodular set cover, ranking, and repeated active learning [PDF]
We propose an online prediction version of submodular set cover with connections to ranking and repeated active learning. In each round, the learning algorithm chooses a sequence of items.

On the Initial Set of Constraints for Graph-Based Submodular Function Maximization
A crucial problem in combinatorial optimization is the submodular function maximization (SFM), and in many cases it involves graphs on which the maximization is specified. The problem is well-studied and hence there are several proposed algorithms in the literature.

On Equivalence of M$^\natural$-concavity of a Set Function and Submodularity of Its Conjugate
A fundamental theorem in discrete convex analysis states that a set function is M$^\natural$-concave if and only if its conjugate function is submodular. This paper gives a new proof to this fact.

Submodular Function Maximization for Group Elevator Scheduling
We propose a novel approach for group elevator scheduling by formulating it as the maximization of submodular function under a matroid constraint. In particular, we propose to model the total waiting time of passengers using a quadratic Boolean function.

Submodular maximization over multiple matroids via generalized exchange properties
In this paper, we consider the problem of maximizing a non-negative submodular function f, defined on a (finite) ground set N, subject to matroid constraints.

Sequence independent lifting for a set of submodular maximization problems
We study the polyhedral structure of a mixed 0-1 set arising from the submodular maximization problem, given by P = {(w, x) ∈ R × {0, 1}n : w ≤ f (x), x ∈ X}, where submodular function f (x) is represented by a concave function composed with an affine ...
