Unified Projection-Free Algorithms for Adversarial DR-Submodular Optimization

no code implementations15 Mar 2024 Mohammad Pedramfar, Yididiya Y. Nadew, Christopher J. Quinn, Vaneet Aggarwal

This paper introduces unified projection-free Frank-Wolfe type algorithms for adversarial continuous DR-submodular optimization, spanning scenarios such as full information and (semi-)bandit feedback, monotone and non-monotone functions, different constraints, and types of stochastic queries.

A Community-Aware Framework for Social Influence Maximization

1 code implementation18 Jul 2022 Abhishek K. Umrawal, Christopher J. Quinn, Vaneet Aggarwal

We propose a community-aware divide-and-conquer framework that involves (i) learning the inherent community structure of the social network, (ii) generating candidate solutions by solving the influence maximization problem for each community, and (iii) selecting the final set of seed nodes using a novel progressive budgeting scheme.

Stochastic Top-$K$ Subset Bandits with Linear Space and Non-Linear Feedback

no code implementations29 Nov 2018 Mridul Agarwal, Vaneet Aggarwal, Christopher J. Quinn, Abhishek K. Umrawal

Many real-world problems like Social Influence Maximization face the dilemma of choosing the best $K$ out of $N$ options at a given time instant.

Directed Information Graphs

no code implementations9 Apr 2012 Christopher J. Quinn, Negar Kiyavash, Todd P. Coleman

We show that under appropriate conditions, it is unique and consistent with another type of graphical model, the directed information graph, which is based on a generalization of Granger causality.
