Continuous submodular function maximization

open access: yesCoRR, 2020
Continuous submodular functions are a category of generally non-convex/non-concave functions with a wide spectrum of applications. The celebrated property of this class of functions - continuous submodularity - enables both exact minimization and approximate maximization in poly. time.

A Min-Max . . . Functions and Its Implications [PDF]

open access: yes, 2014
A. Huber and V. Kolmogorov (ISCO 2012) introduced a concept of k-submodular function as a generalization of ordinary submodular (set) functions and bisubmodular functions and obtained a min-max theorem for minimization of k-submodular functions.

A Submodular Optimization Framework for Imbalanced Text Classification With Data Augmentation

open access: yesIEEE Access, 2023
In the domain of text classification, imbalanced datasets are a common occurrence. The skewed distribution of the labels of these datasets poses a great challenge to the performance of text classifiers.

Locally Adaptive Optimization: Adaptive Seeding for Monotone Submodular Functions [PDF]

open access: yes, 2015
The Adaptive Seeding problem is an algorithmic challenge motivated by influence maximization in social networks: One seeks to select among certain accessible nodes in a network, and then select, adaptively, among neighbors of those nodes as they become ...

Parallel Submodular Function Minimization

open access: yesAdvances in Neural Information Processing Systems 36, 2023
We consider the parallel complexity of submodular function minimization (SFM). We provide a pair of methods which obtain two new query versus depth trade-offs a submodular function defined on subsets of $n$ elements that has integer values between $-M$ and $M$.

Deterministic Algorithms for Submodular Maximization Problems

open access: yes, 2015
Randomization is a fundamental tool used in many theoretical and practical areas of computer science. We study here the role of randomization in the area of submodular function maximization.

Hardness of submodular cost allocation : lattice matching and a simplex coloring conjecture [PDF]

open access: yes, 2014
We consider the Minimum Submodular Cost Allocation (MSCA) problem. In this problem, we are given k submodular cost functions f1, ... , fk: 2V -> R+ and the goal is to partition V into k sets A1, ..., Ak so as to minimize the total cost sumi = 1,k fi(Ai).

NeuSub: A Neural Submodular Approach for Citation Recommendation

open access: yesIEEE Access, 2021
Citation recommendation is a task that aims to automatically select suitable references for a working manuscript. This task has become increasingly urgent as the typical pools of candidates continue to grow, in the order of tens or hundreds of thousands ...

Lazier Than Lazy Greedy [PDF]

open access: yes, 2014
Is it possible to maximize a monotone submodular function faster than the widely used lazy greedy algorithm (also known as accelerated greedy), both in theory and practice?
