Summary

A recent paper published on arXiv explores the complexities of learning in Markovian bandits, particularly focusing on scenarios where states are not observable and decision-making is constrained by specific epochs. The authors introduce a novel concept termed self-degrading Markovian bandits, which addresses the challenges of regret minimization in these settings. They propose the UCB-NOM algorithm, which has been shown to achieve nearly logarithmic regret under certain conditions, highlighting the potential benefits of incorporating prior knowledge about the bandit into the decision-making process.

Takeaways
