Language Grounded Multi-agent Reinforcement Learning with Human-interpretable Communication

NeurIPS 2024poster

Multi-Agent Reinforcement Learning (MARL) methods have shown promise in enabling agents to learn a shared communication protocol from scratch and accomplish challenging team tasks. However, the learned language is usually not interpretable to humans or other agents not co-trained together, limiting…

Theory of Mind for Multi-Agent Collaboration via Large Language Models

EMNLP 2023long main

While Large Language Models (LLMs) have demonstrated impressive accomplishments in both reasoning and planning, their abilities in multi-agent collaborations remains largely unexplored. This study evaluates LLM-based agents in a multi-agent cooperative text game with Theory of Mind (ToM) inference t…
