摘要:

我们研究了具有集中训练和分散执行的多智能体强化学习(MARL)。在训练期间,新的代理可以加入,并且现有代理可以意外地离开训练。在这种情况下,标准的深度MARL模型必须从头开始重新训练,这非常耗时。为了解决这个问题,我们提出了一个特殊的网络架构与少样本学习算法,允许代理的数量在集中训练过程中变化。特别是,当一个新的代理加入集中训练,我们的少样本学习算法训练其策略网络和价值网络使用少量的样本;当一个代理离开训练,其余的代理的训练过程不受影响。我们的实验表明,使用所提出的网络架构和算法,当新代理加入时,模型自适应可以比基线快100倍以上。我们的工作适用于任何环境,包括合作,竞争和混合。

英文摘要:

We study multi-agent reinforcement learning (MARL) with centralized training and decentralized execution. During the training, new agents may join, and existing agents may unexpectedly leave the training. In such situations, a standard deep MARL model must be trained again from scratch, which is very time-consuming. To tackle this problem, we propose a special network architecture with a few-shot learning algorithm that allows the number of agents to vary during centralized training. In particular, when a new agent joins the centralized training, our few-shot learning algorithm trains its policy network and value network using a small number of samples; when an agent leaves the training, the training process of the remaining agents is not affected. Our experiments show that using the proposed network architecture and algorithm, model adaptation when new agents join can be 100+ times faster than the baseline. Our work is applicable to any setting, including cooperative, competitive, and mixed.
