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 $ε$). Our algorithm also succeeds in the agnostic setting.

Concave Aspects of Submodular Functions [PDF]

open access: yes2020 IEEE International Symposium on Information Theory (ISIT), 2020
Submodular Functions are a special class of set functions, which generalize several information-theoretic quantities such as entropy and mutual information [1]. Submodular functions have subgradients and subdifferentials [2] and admit polynomial-time algorithms for minimization, both of which are fundamental characteristics of convex functions ...

Quantitative approximation by nonlinear Angheluta-Choquet singular integrals

open access: yesJournal of Numerical Analysis and Approximation Theory, 2020
By using the concept of nonlinear Choquet integral with respect to a capacity and as a generalization of the Poisson-Cauchy-Choquet operators, we introduce the nonlinear Angheluta-Choquet singular integrals with respect to a family of submodular set ...

A new matroid constructed by the rank function of a matroid

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
In this article, we construct a submodular function using the rank function of a matroid and study induced matroid with constructed polymatroid, then we relate some properties of connectivity of new matroid with the main matroid.

Toward Optimal Placement of Spatial Sensors to Detect Poisson-Distributed Targets

open access: yesIEEE Access, 2023
This paper addresses the challenges of optimally placing a finite number of sensors to detect Poisson-distributed targets in a bounded domain. We seek to rigorously account for uncertainty in the target arrival model throughout the problem.

Mobility-Aware Traffic Offloading via Cooperative Coded Edge Caching

open access: yesIEEE Access, 2020
With caching popular contents at the small-cell base stations (SBSs), cooperative edge caching has emerged as an effective approach to offload explosively increasing network traffic from a massive number of users in mobile edge networks (MENs).

Differentially Private Decomposable Submodular Maximization

open access: yes, 2020
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.

Streaming Algorithms for News and Scientific Literature Recommendation: Monotone Submodular Maximization With a $d$ -Knapsack Constraint

open access: yesIEEE Access, 2018
Submodular optimization plays a significant role in combinatorial problems, since it captures the structure of the edge cuts in graphs, the coverage of sets, and so on. Many data mining and machine learning problems can be cast as submodular maximization

Approximation Algorithm for the Single Machine Scheduling Problem with Release Dates and Submodular Rejection Penalty

open access: yesMathematics, 2020
In this paper, we consider the single machine scheduling problem with release dates and nonmonotone submodular rejection penalty. We are given a single machine and multiple jobs with probably different release dates and processing times. For each job, it
