Combining Tree-Search, Generative Models, and Nash Bargaining Concepts in Game-Theoretic Reinforcement Learning

Explore a DS4DM Coffee Talk presentation on combining tree-search, generative models, and Nash bargaining concepts in game-theoretic reinforcement learning. Delve into the augmentation of Policy-Space Response Oracles (PSRO) with a novel search procedure using generative sampling of world states and new meta-strategy solvers based on the Nash bargaining solution. Examine the evaluation of PSRO's ability to compute approximate Nash equilibrium and its performance in negotiation games like Colored Trails and Deal or No Deal. Learn about behavioral studies involving human participants negotiating with AI agents, and discover how search with generative modeling enhances policy strength, enables online Bayesian co-player prediction, and produces agents capable of achieving comparable social welfare in human-AI negotiations.
