A Unified Framework for Locality in Scalable MARL
Researchers have developed a new unified framework for analyzing locality in scalable multi-agent reinforcement learning (MARL). This framework improves upon existing methods by decoupling environment sensitivity from policy sensitivity, allowing for more precise locality guarantees. The new approach uses the spectral radius of a combined matrix to control the decay of average-reward solutions, offering a stricter bound than previous techniques. AI
