摘要:

平均场理论提供了一种有效的方法来扩展多智能体强化学习算法的环境与许多代理,可以抽象的虚拟平均代理。在本文中,我们将平均场多智能体算法扩展到多种类型。这些类型可以放松平均场强化学习中的一个核心假设,即环境中的所有智能体都在使用几乎相似的策略,并且具有相同的目标。我们进行了三个不同的测试平台上的许多代理强化学习领域的实验,基于标准的MATRIX框架。我们考虑两种不同类型的平均场环境:a)代理属于先验已知的预定义类型的游戏和b)每个代理的类型未知的游戏,因此必须根据观察来学习。我们为每种类型的游戏引入新的算法,并证明其优越的性能超过最先进的算法,假设所有代理属于同一类型和其他基线算法的MAgent框架。

英文摘要:

Mean field theory provides an effective way of scaling multiagent reinforcement learning algorithms to environments with many agents that can be abstracted by a virtual mean agent. In this paper, we extend mean field multiagent algorithms to multiple types. The types enable the relaxation of a core assumption in mean field reinforcement learning, which is that all agents in the environment are playing almost similar strategies and have the same goal. We conduct experiments on three different testbeds for the field of many agent reinforcement learning, based on the standard MAgents framework. We consider two different kinds of mean field environments: a) Games where agents belong to predefined types that are known a priori and b) Games where the type of each agent is unknown and therefore must be learned based on observations. We introduce new algorithms for each type of game and demonstrate their superior performance over state of the art algorithms that assume that all agents belong to the same type and other baseline algorithms in the MAgent framework.
