Integrating organizational control into multi-agent learning

Multi-Agent Reinforcement Learning (MARL) algorithms suffer from slow convergence and even divergence, especially in largescale systems. In this work, we develop an organization-based control framework to speed up the convergence of MARL algorithms in a network of agents. Our framework defines a multi-level organizational structure for automated supervision and a communication protocol for exchanging information between lower-level nd higher-level supervising agents. The abstracted states of lower-level agents travel upwards so that higher-level supervising agents generate a broader view of the state of the network. This broader view is used in creating supervisory information which is passed down the hierarchy. The supervisory policy adaptation then integrates supervisory information into existing MARL algorithms, guiding agents’ exploration of their state-action space. The generality of our framework is verified by its applications on different domains (distributed task allocati...
