Interactive submodular set cover

open access: yes, 2010
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.

Submodular maximization and its generalization through an intersection cut lens

open access: yes, 2023
We study a mixed-integer set $S:=\{(x,t) \in \{0,1\}^n \times \mathbb{R}: f(x) \ge t\}$ arising in the submodular maximization problem, where $f$ is a submodular function defined over $\{0,1\}^n$.

Combinatorial Algorithms for Submodular Function Minimization and Related Problems [PDF]

open access: yes, 2015
Submodular functions are common in combinatorics; examples include the cut capacity function of a graph and the rank function of a matroid. The submodular function minimization problem generalizes the classical minimum cut problem and also contains a ...

Universal set families for maximization of nonnegative submodular and XOS functions

open access: yes
We consider the question of designing a universal family of sets $F \subset 2^{[n]}$ such that for any function $f:2^{[n]} \to R_{\geq 0}$ in a certain class, we have $$\max_{S \in F} f(S) \geq c(n) \cdot \max_{S \subset [n]} f(S).$$ We prove that there is a family of subpolynomial size such that for any nonnegative submodular function, $c(n) = Ω ...

Distributionally robust submodular maximization

open access: yes, 2020
Submodular functions have applications throughout machine learning, but in many settings, we do not have direct access to the underlying function f. We focus on stochastic functions that are given as an expectation of functions over a distribution P.

Submodular maximization and its generalization through an intersection cut lens

open access: yes
International audienceWe study a mixed-integer set $S:={(x,t)∈{0,1}^n \times \mathbf{R}:f(x)≥t}$ arising in the submodular maximization problem, where $f$ is a submodular function defined over ${0,1}^n$.
