AI总结:

本文研究基于模型的深度强化学习在 Robot Air Hockey Challenge 2023 中的应用,通过稀疏奖励与自博弈训练智能体自主打冰球,发现自博弈可提升泛化能力且更长想象视界能带来更稳定的学习与更优性能。

摘要:

在应对 Robot Air Hockey Challenge 2023 的背景下,我们研究了基于模型的深度强化学习的适用性,以获取能够自主打冰球的策略。我们的智能体仅从稀疏奖励中学习,同时结合自博弈以随时间迭代地改进其行为。机器人操作器使用连续高层动作进行笛卡尔平面上基于位置的控制,同时对环境具有部分可观测性且存在随机状态转移。我们证明,当智能体仅针对单一打法进行训练时容易过拟合,这凸显了自博弈对于泛化到未见对手新策略的重要性。此外,在高度动态的冰球比赛这一竞争环境中,我们探讨了想象视界的影响,更长的视界带来了更稳定的学习和更好的整体性能。

英文摘要:

In the context of addressing the Robot Air Hockey Challenge 2023, we investigate the applicability of model-based deep reinforcement learning to acquire a policy capable of autonomously playing air hockey. Our agents learn solely from sparse rewards while incorporating self-play to iteratively refine their behaviour over time. The robotic manipulator is interfaced using continuous high-level actions for position-based control in the Cartesian plane while having partial observability of the environment with stochastic transitions. We demonstrate that agents are prone to overfitting when trained solely against a single playstyle, highlighting the importance of self-play for generalization to novel strategies of unseen opponents. Furthermore, the impact of the imagination horizon is explored in the competitive setting of the highly dynamic game of air hockey, with longer horizons resulting in more stable learning and better overall performance.
