Will lecture on

Learning to Cooperate and Compete in Diplomacy
AI has made incredible progress in purely adversarial games such as chess, go, and poker. However, the real world involves a complex mixture of cooperation and competition, sometimes with irrational or suboptimal participants, and in these settings past AI techniques fall apart. For this reason, Diplomacy, a popular game focused on negotiation and alliance-building, has served as a long-standing grand challenge for AI that requires radically different techniques compared to prior games and has major implications if AI algorithms eventually succeed. In this talk I will describe Diplomacy and cover recent research results that have allowed our group to achieve expert-level human performance in the no-communication version of this game via a combination of imitation learning on human data and self-play reinforcement learning. In particular, I will cover a new regret minimization technique that converges to a coarse correlated equilibrium regularized toward a human prior. I will conclude with a discussion of the challenges that await as research shifts toward versions of the game in which players can privately communicate and therefore correlate their actions.
