Learning in games: fictitious play dynamics
Nettet18. aug. 2016 · Abstract. We investigate a class of reinforcement learning dynamics where players adjust their strategies based on their actions’ cumulative payoffs over time—specifically, by playing mixed strategies that maximize their expected cumulative payoff minus a regularization term. A widely studied example is exponential … NettetThe class of dynamics under consideration includes fictitious play and its regularized variants, the best reply dynamics (again, possibly regularized), as well as the dynamics of dual averaging / "follow the regularized leader" (which themselves include as special cases the replicator dynamics and Friedman's projection dynamics).
