合作多智能体系统中的独立生成对抗自模仿学习

Independent Generative Adversarial Self-Imitation Learning in Cooperative Multiagent Systems

Xiaotian Hao, Weixun Wang, Jianye Hao, Yaodong Yang

摘要:

实践中的许多任务需要多个智能体通过强化学习进行协作。一般来说,合作多智能体强化学习算法可以分为两种范式:联合行动学习者(JAL)和独立学习者(IL)。在许多实际应用中,代理人无法观察其他代理人的行为和奖励,使JAL不适用。在这项工作中,我们专注于独立的学习范式,其中每个代理仅根据其局部观察做出决策。然而,学习是具有挑战性的,在独立的设置,由于所有代理的本地观点,认为世界是一个非静止的环境,由于同时探索的队友。在本文中,我们提出了一个新的框架称为独立生成对抗自我模仿学习(IGASIL),以解决在完全合作的多智能体环境中的协调问题。据我们所知,我们是第一个将自模仿学习与生成对抗模仿学习(GAIL)结合起来,并将其应用于合作多智能体系统的人。此外,我们还提出了子课程经验回放机制,以尽可能多地提取过去的有益经验,加速自我模仿学习过程。在星际争霸单元微管理测试平台和普遍采用的基准测试中进行的评估表明,我们的IGASIL产生了最先进的结果,甚至在收敛速度和最终性能方面优于JAL。

英文摘要:

Many tasks in practice require the collaboration of multiple agents through reinforcement learning. In general, cooperative multiagent reinforcement learning algorithms can be classified into two paradigms: Joint Action Learners (JALs) and Independent Learners (ILs). In many practical applications, agents are unable to observe other agents' actions and rewards, making JALs inapplicable. In this work, we focus on independent learning paradigm in which each agent makes decisions based on its local observations only. However, learning is challenging in independent settings due to the local viewpoints of all agents, which perceive the world as a non-stationary environment due to the concurrently exploring teammates. In this paper, we propose a novel framework called Independent Generative Adversarial Self-Imitation Learning (IGASIL) to address the coordination problems in fully cooperative multiagent environments. To the best of our knowledge, we are the first to combine self-imitation learning with generative adversarial imitation learning (GAIL) and apply it to cooperative multiagent systems. Besides, we put forward a Sub-Curriculum Experience Replay mechanism to pick out the past beneficial experiences as much as possible and accelerate the self-imitation learning process. Evaluations conducted in the testbed of StarCraft unit micromanagement and a commonly adopted benchmark show that our IGASIL produces state-of-the-art results and even outperforms JALs in terms of both convergence speed and final performance.
