The multi-armed bandit model effectively describes a wide range of online decision-making problems such as identifying the most effective treatment in clinical trial, finding the advertisement which is more likely to be clicked in a web advertising platform, discovering the shortest path in a graph, and so on. In this talk, we will cover some recent advancements in the multi-armed bandit extending the standard setting to novel problems such as the best-arm identification (eg, returning the best treatment after a finite number of patients), active bandit setting (eg, accurate estimation of the reliability of different production lines), and the application of bandits to strategic settings (eg, web advertising).
