摘要:
多模态学习显著推动了生成式AI的发展,尤其是在视觉-语言建模方面。GPT-4V等创新成果以及LLaVA等开源项目已经促成了能够完成零样本任务的强大对话智能体。然而,将这些技术应用于生物医学领域会带来独特挑战。LLaVA-Med等近期计划已开始利用PMC-15M等大型数据集,使指令微调适配生物医学情境。我们的研究提供三项关键贡献:(i)我们提出一个新的指令数据集,其中丰富了来自Claude3-Opus和LLaMA3 70B的医学图像-文本对;(ii)我们提出一种新颖的图像编码策略,利用层级表示来改进细粒度生物医学视觉理解;(iii)我们开发了Llama3-Med模型,该模型在生物医学视觉问答基准上取得最先进的零样本性能,与以往方法相比平均性能提升超过10%。这些进展为医疗专业人员提供了更准确、可靠的工具,弥补了当前多模态对话助手的差距,并推动医学AI的进一步创新。
英文摘要:
Multi-modal learning has significantly advanced generative AI, especially in vision-language modeling. Innovations like GPT-4V and open-source projects such as LLaVA have enabled robust conversational agents capable of zero-shot task completions. However, applying these technologies in the biomedical field presents unique challenges. Recent initiatives like LLaVA-Med have started to adapt instruction-tuning for biomedical contexts using large datasets such as PMC-15M. Our research offers three key contributions: (i) we present a new instruct dataset enriched with medical image-text pairs from Claude3-Opus and LLaMA3 70B, (ii) we propose a novel image encoding strategy using hierarchical representations to improve fine-grained biomedical visual comprehension, and (iii) we develop the Llama3-Med model, which achieves state-of-the-art zero-shot performance on biomedical visual question answering benchmarks, with an average performance improvement of over 10% compared to previous methods. These advancements provide more accurate and reliable tools for medical professionals, bridging gaps in current multi-modal conversational assistants and promoting further innovations in medical AI.
