摘要:

大型语言模型(LLMs)作为自主智能体,通过知识驱动的方式为解决现实世界挑战提供了一条新途径。这些基于LLM增强的方法在泛化能力和可解释性方面表现出色。然而,驾驶任务的复杂性通常需要多个异构智能体的协作,这凸显了此类LLM驱动的智能体进行合作性知识共享和认知协同的必要性。尽管LLMs前景广阔,但当前的应用主要集中在单智能体场景。为了拓宽知识驱动策略的视野并增强自主智能体的泛化能力,我们提出了KoMA框架,该框架由多智能体交互、多步规划、共享记忆和基于排名的反思模块组成,以增强复杂驾驶场景中多智能体的决策能力。基于该框架生成的驾驶场景文本描述,多智能体交互模块使LLM智能体能够像人类认知一样分析和推断周围车辆的意图。多步规划模块使LLM智能体能够逐层分析并获得最终行动决策,以确保短期行动决策的目标一致性。共享记忆模块可以积累集体经验以做出更优决策,而基于排名的反思模块可以评估和改进智能体行为,旨在提升驾驶安全性和效率。KoMA框架不仅增强了自动驾驶智能体的鲁棒性和适应性,还显著提升了它们在不同场景中的泛化能力。实证结果表明,我们的方法优于传统方法,特别是在无需大量重新训练的情况下处理复杂、不可预测的驾驶环境方面。

英文摘要:

Large language models (LLMs) as autonomous agents offer a novel avenue for tackling real-world challenges through a knowledge-driven manner. These LLM-enhanced methodologies excel in generalization and interpretability. However, the complexity of driving tasks often necessitates the collaboration of multiple, heterogeneous agents, underscoring the need for such LLM-driven agents to engage in cooperative knowledge sharing and cognitive synergy. Despite the promise of LLMs, current applications predominantly center around single agent scenarios. To broaden the horizons of knowledge-driven strategies and bolster the generalization capabilities of autonomous agents, we propose the KoMA framework consisting of multi-agent interaction, multi-step planning, shared-memory, and ranking-based reflection modules to enhance multi-agents' decision-making in complex driving scenarios. Based on the framework's generated text descriptions of driving scenarios, the multi-agent interaction module enables LLM agents to analyze and infer the intentions of surrounding vehicles, akin to human cognition. The multi-step planning module enables LLM agents to analyze and obtain final action decisions layer by layer to ensure consistent goals for short-term action decisions. The shared memory module can accumulate collective experience to make superior decisions, and the ranking-based reflection module can evaluate and improve agent behavior with the aim of enhancing driving safety and efficiency. The KoMA framework not only enhances the robustness and adaptability of autonomous driving agents but also significantly elevates their generalization capabilities across diverse scenarios. Empirical results demonstrate the superiority of our approach over traditional methods, particularly in its ability to handle complex, unpredictable driving environments without extensive retraining.
