The rapid evolution of vision-language models (VLMs), such as CLIP, has demonstrated remarkable zero-shot capabilities in downstream tasks. Prompt learning paradigms like Context Optimization (CoOp) refine learnable prompts for efficient adaptation. However, their application in the biomedical domain remains limited due to the insufficient utilization of specialized biomedical knowledge and cross-modality structural relationships. To address these, we introduce MeDKCoOp, a Medical Dual Knowledge-guided graph adaptation method that leverages systematic integration of knowledge through three aspects: exploit domain-specific knowledge from both textual and visual branches, formalize it into graph-structured representations, and leverage knowledge-guided relation transfer for learning cross-modality fusion. By dynamically optimizing learnable prompts through relation learning process, our method …
本文提出MeDKCoOp，一种面向生物医学视觉语言模型的双知识引导图提示学习方法。该方法系统整合医学领域知识，从文本与视觉分支提取专门知识并构建图结构表示，通过知识引导的关系转移实现跨模态融合，并动态优化可学习提示，以增强CLIP等模型在医学下游任务中的适应能力。实验表明其在多个生物医学基准上取得优异性能。
