Multi-agent learning via gradient ascent activity-based credit assignment

Sci Rep. 2023 Sep 14;13(1):15256. doi: 10.1038/s41598-023-42448-9.

Abstract

We consider the situation in which cooperating agents learn to achieve a common goal based solely on a global return that results from all agents' behavior. The method proposed is based on taking into account the agents' activity, which can be any additional information to help solving multi-agent decentralized learning problems. We propose a gradient ascent algorithm and assess its performance on synthetic data.
