📝 摘要(中文)
大型语言模型(LLMs)在各种推理和生成任务中展现了卓越的能力。然而,它们在复杂因果推理、发现和估计方面的能力仍在积极发展中,常常受到幻觉、依赖虚假相关性以及处理细微、领域特定或个性化因果关系的困难等问题的制约。多智能体系统利用多个基于LLM的智能体的协作或专业能力,成为解决这些限制的强大范式。本文综述了因果多智能体LLMs的快速发展,探讨了这些系统如何设计以应对因果推理、反事实分析、数据中的因果发现和因果效应估计等不同方面。我们还讨论了多样的架构模式和交互协议,以及评估方法、基准和因果多智能体LLMs的应用领域,包括科学发现、医疗、事实核查和个性化系统。最后,强调了持续的挑战、开放的研究问题和未来的有希望方向。

📄 摘要(原文)
Large Language Models (LLMs) have demonstrated remarkable capabilities in various reasoning and generation tasks. However, their proficiency in complex causal reasoning, discovery, and estimation remains an area of active development, often hindered by issues like hallucination, reliance on spurious correlations, and difficulties in handling nuanced, domain-specific, or personalized causal relationships. Multi-agent systems, leveraging the collaborative or specialized abilities of multiple LLM-based agents, are emerging as a powerful paradigm to address these limitations. This review paper explores the burgeoning field of causal multi-agent LLMs. We examine how these systems are designed to tackle different facets of causality, including causal reasoning and counterfactual analysis, causal discovery from data, and the estimation of causal effects. We delve into the diverse architectural patterns and interaction protocols employed, from pipeline-based processing and debate frameworks to simulation environments and iterative refinement loops. Furthermore, we discuss the evaluation methodologies, benchmarks, and diverse application domains where causal multi-agent LLMs are making an impact, including scientific discovery, healthcare, fact-checking, and personalized systems. Finally, we highlight the persistent challenges, open research questions, and promising future directions in this synergistic field, aiming to provide a comprehensive overview of its current state and potential trajectory.
