Tail Distribution of Regret in Optimistic Reinforcement Learning
NeutralArtificial Intelligence
- A new study has derived instance-dependent tail bounds for the regret associated with optimism-based reinforcement learning in finite-horizon tabular Markov decision processes. The research focuses on a UCBVI-type algorithm, characterizing the tail distribution of cumulative regret over multiple episodes, revealing a two-regime structure in the tail behavior.
- This development is significant as it enhances the understanding of regret in reinforcement learning, providing clearer insights into the performance of algorithms under uncertainty, which is crucial for applications in various fields such as robotics and automated decision-making.
- The findings contribute to ongoing discussions in the field of artificial intelligence regarding exploration strategies and regret minimization, paralleling advancements in related areas such as deep reinforcement learning and optimization techniques, which aim to address complex challenges in dynamic environments.
