摘要:

场景图已成为一种结构化且可序列化的环境表示,用于大语言模型(LLM)的具身空间推理。在这项工作中,我们提出了SG^2,一个基于多智能体LLM的迭代模式引导场景图推理框架。这些智能体被分为两个模块:(1)Reasoner模块,用于抽象任务规划和图信息查询生成;(2)Retriever模块,用于根据查询遵循代码编写提取相应的图信息。两个模块迭代协作,实现顺序推理和对图信息的自适应关注。提示给两个模块的场景图模式不仅简化了推理和检索过程,还指导了两个模块间的合作。这消除了用完整图数据提示LLM的需求,降低了因无关信息产生幻觉的几率。通过在多个模拟环境中的实验,我们表明我们的框架在数值问答和规划任务中超越了现有的基于LLM的方法和基线单智能体、基于工具的边推理边检索策略。

英文摘要:

Scene graphs have emerged as a structured and serializable environment representation for grounded spatial reasoning with Large Language Models (LLMs). In this work, we propose SG^2, an iterative Schema-Guided Scene-Graph reasoning framework based on multi-agent LLMs. The agents are grouped into two modules: a (1) Reasoner module for abstract task planning and graph information queries generation, and a (2) Retriever module for extracting corresponding graph information based on code-writing following the queries. Two modules collaborate iteratively, enabling sequential reasoning and adaptive attention to graph information. The scene graph schema, prompted to both modules, serves to not only streamline both reasoning and retrieval process, but also guide the cooperation between two modules. This eliminates the need to prompt LLMs with full graph data, reducing the chance of hallucination due to irrelevant information. Through experiments in multiple simulation environments, we show that our framework surpasses existing LLM-based approaches and baseline single-agent, tool-based Reason-while-Retrieve strategy in numerical Q\&A and planning tasks.
