title: Learning Predictive Communication by Imagination in Networked System Control
abstract: Dealing with multi-agent control in networked systems is one of the biggest challenges in Reinforcement Learning (RL) and limited success has been presented compared to recent deep reinforcement learning in single-agent domain. However, obstacles remain in addressing the delayed global information where each agent learns a decentralized control policy based on local observations and messages from connected neighbors. This paper first considers delayed global information sharing by combining the delayed global information and latent imagination of farsighted states in differentiable communication. Our model allows an agent to imagine its future states and communicate that with its neighbors. The predictive message sent to the connected neighbors reduces the delay in global information.  On the tasks of networked multi-agent traffic control, experimental results show that our model helps stabilize the training of each local agent and outperforms existing algorithms for networked system control.
