From Explicit Communication to Tacit Cooperation:A Novel Paradigm for Cooperative MARL

Understand

Centralized training with decentralized execution (CTDE) is a widely-used learning paradigm that has achieved significant success in complex tasks.

• However, partial observability issues and the absence of effectively shared signals between agents often limit its effectiveness in fostering cooperation.
• While communication can address this challenge, it simultaneously reduces the algorithm's practicality.
• Drawing inspiration from human team cooperative learning, we propose a novel paradigm that facilitates a gradual shift from explicit communication to tacit cooperation.
