摘要:

多智能体强化学习的成功部署通常需要智能体适应其行为。在本研究中,我们探讨了团队协作适应问题,即一组智能体需要调整其策略以在有限微调的情况下解决新任务。基于智能体需要能够识别和区分任务才能适应当前任务的直觉,我们提出学习多智能体任务嵌入(MATE)。这些任务嵌入使用针对重建唯一标识任务的转移函数和奖励函数而优化的编码器-解码器架构进行训练。我们证明,当提供任务嵌入时,智能体团队能够适应新任务。我们提出了三种MATE训练范式:独立MATE、集中式MATE和混合MATE,它们在用于任务编码的信息上有所不同。我们表明MATE学习到的嵌入能够识别任务,并提供智能体在适应新任务期间利用的有用信息。

英文摘要:

Successful deployment of multi-agent reinforcement learning often requires agents to adapt their behaviour. In this work, we discuss the problem of teamwork adaptation in which a team of agents needs to adapt their policies to solve novel tasks with limited fine-tuning. Motivated by the intuition that agents need to be able to identify and distinguish tasks in order to adapt their behaviour to the current task, we propose to learn multi-agent task embeddings (MATE). These task embeddings are trained using an encoder-decoder architecture optimised for reconstruction of the transition and reward functions which uniquely identify tasks. We show that a team of agents is able to adapt to novel tasks when provided with task embeddings. We propose three MATE training paradigms: independent MATE, centralised MATE, and mixed MATE which vary in the information used for the task encoding. We show that the embeddings learned by MATE identify tasks and provide useful information which agents leverage during adaptation to novel tasks.
