In Proceedings of the 35th International Conference on Machine Learning (Proceedings of Machine Learning Research), Vol. 80. PMLR,, 1861–1870. Google Scholar Web25 de set. de 2024 · The hierarchical interaction between the actor and critic in actor-critic based reinforcement learning algorithms naturally lends itself to a game-theoretic interpretation. We adopt this viewpoint and model the actor and critic interaction as a two-player general-sum game with a leader-follower structure known as a Stackelberg game.
