State Action Space

State-action space, in reinforcement learning, refers to the combined set of all possible states an agent can be in and the actions it can take. Research focuses on efficiently exploring and representing this space, particularly in continuous domains, using techniques like Thompson sampling for optimistic exploration, adaptive discretization, and low-rank tensor approximations for value function estimation. These advancements aim to improve the sample efficiency and robustness of reinforcement learning algorithms, impacting fields like robotics, multi-agent systems, and healthcare where efficient learning from limited data is crucial.
