Primal-Dual Algorithms with Predictions for Online Bounded Allocation and Ad-Auctions Problems

no code implementations13 Feb 2024 Eniko Kevi, Nguyen Kim Thang

We constructed primal-dual algorithms that achieve competitive performance depending on the quality of the predictions.

Handling Delayed Feedback in Distributed Online Optimization : A Projection-Free Approach

1 code implementation3 Feb 2024 Tuan-Anh Nguyen, Nguyen Kim Thang, Denis Trystram

Learning at the edges has become increasingly important as large quantities of data are continually generated locally.

Online Decentralized Frank-Wolfe: From theoretical bound to applications in smart-building

no code implementations31 Jul 2022 Angan Mitra, Nguyen Kim Thang, Tuan-Anh Nguyen, Denis Trystram, Paul Youssef

The design of decentralized learning algorithms is important in the fast-growing world in which data are distributed over participants with limited local computation resources and communication.

Online Primal-Dual Algorithms with Predictions for Packing Problems

no code implementations1 Oct 2021 Nguyen Kim Thang, Christoph Durr

The domain of online algorithms with predictions has been extensively studied for different applications such as scheduling, caching (paging), clustering, ski rental, etc.

Online Non-Monotone DR-submodular Maximization

no code implementations25 Sep 2019 Nguyen Kim Thang, Abhinav Srivastav

First, we present an online algorithm that achieves a $1/e$-approximation ratio with the regret of $O(T^{2/3})$ for maximizing DR-submodular functions over any down-closed convex set.

Online learning for min-max discrete problems

no code implementations12 Jul 2019 Evripidis Bampis, Dimitris Christou, Bruno Escoffier, Nguyen Kim Thang

We show that for different nonlinear discrete optimization problems, it is strongly $NP$-hard to solve the offline optimization oracle, even for problems that can be solved in polynomial time in the static case (e. g. min-max vertex cover, min-max perfect matching, etc.).

Non-monotone DR-submodular Maximization: Approximation and Regret Guarantees

no code implementations23 May 2019 Christoph Dürr, Nguyen Kim Thang, Abhinav Srivastav, Léo Tible

In this paper, we study the fundamental problem of maximizing non-monotone DR-submodular functions over down-closed and general convex sets in both offline and online settings.
