Weakly Submodular Functions [PDF]

open access: yes, 2014
Submodular functions are well-studied in combinatorial optimization, game theory and economics. The natural diminishing returns property makes them suitable for many applications. We study an extension of monotone submodular functions, which we call {\em

Resilient Monotone Submodular Function Maximization [PDF]

open access: yes2017 IEEE 56th Annual Conference on Decision and Control (CDC), 2017
In this paper, we focus on applications in machine learning, optimization, and control that call for the resilient selection of a few elements, e.g. features, sensors, or leaders, against a number of adversarial denial-of-service attacks or failures.

Learning submodular functions [PDF]

open access: yesProceedings of the forty-third annual ACM symposium on Theory of computing, 2011
There has been much interest in the machine learning and algorithmic game theory communities on understanding and using submodular functions. Despite this substantial interest, little is known about their learnability from data. Motivated by applications, such as pricing goods in economics, this paper considers PAC-style learning of submodular ...

Submodular function minimization and polarity [PDF]

open access: yesMathematical Programming, 2021
Using polarity, we give an outer polyhedral approximation for the epigraph of set functions. For a submodular function, we prove that the corresponding polar relaxation is exact; hence, it is equivalent to the Lov sz extension. The polar approach provides an alternative proof for the convex hull description of the epigraph of a submodular function ...

Subquadratic submodular function minimization [PDF]

open access: yesProceedings of the 49th Annual ACM SIGACT Symposium on Theory of Computing, 2017
Submodular function minimization (SFM) is a fundamental discrete optimization problem which generalizes many well known problems, has applications in various fields, and can be solved in polynomial time. Owing to applications in computer vision and machine learning, fast SFM algorithms are highly desirable. The current fastest algorithms [Lee, Sidford,

Submodular Functions are Noise Stable [PDF]

open access: yesProceedings of the Twenty-Third Annual ACM-SIAM Symposium on Discrete Algorithms, 2012
We show that all non-negative submodular functions have high {\em noise-stability}. As a consequence, we obtain a polynomial-time learning algorithm for this class with respect to any product distribution on $\{-1,1\}^n$ (for any constant accuracy parameter $ $). Our algorithm also succeeds in the agnostic setting. Previous work on learning submodular

A Combinatorial 2-Approximation Algorithm for the Parallel-Machine Scheduling with Release Times and Submodular Penalties

open access: yesMathematics, 2021
In this paper, we consider parallel-machine scheduling with release times and submodular penalties (P|rj,reject|Cmax+π(R)), in which each job can be accepted and processed on one of m identical parallel machines or rejected, but a penalty must paid if a ...

A Combinatorial Approximation Algorithm for the Vector Scheduling with Submodular Penalties on Parallel Machines

open access: yesJournal of Mathematics, 2023
In this paper, we focus on solving the vector scheduling problem with submodular penalties on parallel machines. We are given n jobs and m parallel machines, where each job is associated with a d-dimensional vector.
