ArogyaSutra:面向印度语言多模态医疗推理的多智能体框架
阅读原文· arxiv.org为应对印度农村患者用本土语言和医学影像表达复杂病情,研究团队构建了ArogyaBodha数据集,包含8个异构来源、31个身体系统、6种成像模态、21个临床领域,覆盖英语和7种主要印度语言。同时提出ArogyaSutra,一个基于Actor-Critic的多智能体框架,集成工具接地与双记忆机制,实现逐步推理感知决策,并利用存储的Actor-Critic仿真轨迹进行知识蒸馏。实验表明,该数据集与框架在所有印度语言上均提升了多语言医疗推理准确性。源代码与数据集已开源。
Multimodal Large Language Models (MLLMs) have shown promising reasoning capabilities in general domains, yet their performance remains limited in specialized settings such as healthcare, especially in multilingual and low-resource scenarios. This gap is critical in regions like rural India, where patients often express complex medical queries in native Indic languages and rely on multimodal inputs such as medical images. Existing English-centric MLLMs struggle to support such use cases, limiting equitable access to AI-driven healthcare assistance. To address this challenge, we introduce ArogyaBodha, a large-scale multilingual multimodal medical question-answer dataset constructed from eight heterogeneous sources, covering 31 body systems, six imaging modalities, and 21 clinical domains across English and seven major Indian languages. We further propose ArogyaSutra, an actor-critic-based multi-agent framework that integrates tool grounding with dual-memory mechanisms for step-wise, reasoning-aware decision making, and uses stored actor-critic simulation trajectories for distillation. Experiments show that our dataset and framework improve multilingual medical reasoning accuracy across all Indic languages, with ablations validating the contribution of each component.
