Online Learning with Recency: Algorithms for Sliding-window Streaming Multi-armed Bandits

Vladimir Braverman, Chen Wang, Liudeng Wang +1

Motivated by the recency effect in online learning, we study algorithms for single-pass *sliding-window streaming multi-armed bandits (MABs)* in this paper. In this setting, we are…

Fully Dynamic Adversarially Robust Correlation Clustering in Polylogarithmic Update Time

Vladimir Braverman, Prathamesh Dharangutte, Shreyas Pai +2

We study the dynamic correlation clustering problem with edge label flips. In correlation clustering, we are given a -vertex complete graph whose edges are l…

Online Learning with Limited Information in the Sliding Window Model

Vladimir Braverman, Sumegha Garg, Chen Wang +2

Motivated by recent work on the experts problem in the streaming model, we consider the experts problem in the sliding window model. The sliding window model is a well-studied mode…

Relative Error Fair Clustering in the Weak-Strong Oracle Model

Vladimir Braverman, Prathamesh Dharangutte, Shaofeng H. -C. Jiang +4

We study fair clustering problems in a setting where distance information is obtained from two sources: a strong oracle providing exact distances, but at a high cost, and a weak or…

Learning-Augmented Hierarchical Clustering

Vladimir Braverman, Jon C. Ergun, Chen Wang +1

Hierarchical clustering (HC) is an important data analysis technique in which the goal is to recursively partition a dataset into a tree-like structure while grouping together simi…

Learning-augmented Maximum Independent Set

Vladimir Braverman, Prathamesh Dharangutte, Vihan Shah +1

We study the Maximum Independent Set (MIS) problem on general graphs within the framework of learning-augmented algorithms. The MIS problem is known to be NP-hard and is also NP-ha…
