Mini-tutorial: Essential concepts of multi-agent learning Gerald Tesauro IBM T. J. Watson Research Center This talk will provide an introductory description of the problems and open issues in multi-agent learning. Basic concepts in reinforcement learning and game theory are covered, followed by a survey of a variety of approaches currently being studied by researchers. These approaches are grouped roughly into two categories: "naive" approaches such as fictitious play and evolutionary game theory, that ignore non-stationary of other agents' play, and more "sophisticated" approaches such as WoLF and "strategic teaching," that implicitly or explicitly allow for such non-stationarity.
