A Genetic Algorithm-based Framework for Learning Statistical Power Manifold

no code implementations1 Sep 2022 Abhishek K. Umrawal, Sean P. Lane, Erin P. Hennes

We also show that the quality of learning the manifold improves as the number of iterations increases for the genetic algorithm.

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.

On Parameter Estimation in Unobserved Components Models subject to Linear Inequality Constraints

no code implementations23 Oct 2021 Abhishek K. Umrawal, Joshua C. C. Chan

We propose a new \textit{quadratic programming-based} method of approximating a nonstandard density using a multivariate Gaussian density.

FlexPool: A Distributed Model-Free Deep Reinforcement Learning Algorithm for Joint Passengers & Goods Transportation

no code implementations27 Jul 2020 Kaushik Manchella, Abhishek K. Umrawal, Vaneet Aggarwal

Through simulations on a realistic multi-agent urban mobility platform, we demonstrate that FlexPool outperforms other model-free settings in serving the demands from passengers & goods.

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.
