DAL: A Practical Prior-Free Black-Box Framework for Piecewise Stationary Bandits

ICML 2026poster

We introduce a practical, black-box framework termed Detection Augmented Learning (DAL) for the problem of piecewise stationary bandits without knowledge of the underlying non-stationarity. DAL accepts any stationary bandit algorithm with order-optimal regret as input and augments it with a change d…

Is Prior-Free Black-Box Non-Stationary Reinforcement Learning Feasible?

AISTATS 2025poster

We study the problem of Non-Stationary Reinforcement Learning (NS-RL) without prior knowledge about the system’s non-stationarity. A state-of-the-art, black-box algorithm, known as MASTER, is considered, with a focus on identifying the conditions under which it can achieve its stated goals. Specific…

Track-MDP: Reinforcement Learning for Target Tracking with Controlled Sensing

ICASSP 2025accepted

State of the art methods for target tracking with sensor management (or controlled sensing) are model-based and are obtained through solutions to Partially Observable Markov Decision Process (POMDP) formulations. In this paper a Reinforcement Learning (RL) approach to the problem is explored for the…
