AI总结:

本文提出ViP框架,通过视觉症状生成器和双提示网络从CLIP迁移一般知识,在医学图像分析中超越现有最先进方法。

摘要:

像CLIP这样的预训练大型视觉-语言模型(VLMs)已经利用自然语言作为监督彻底改变了视觉表示学习,并展示出有前景的泛化能力。在这项工作中,我们提出了ViP,一种用于医学图像分析的新型视觉症状引导提示学习框架,它促进了从CLIP迁移一般知识。ViP由两个关键组件组成:视觉症状生成器(VSG)和双提示网络。具体来说,VSG旨在从预训练的大型语言模型中提取可解释的视觉症状,而双提示网络利用这些视觉症状来指导两个可学习提示模块的训练,即上下文提示和合并提示,这有效地使我们的框架通过大型VLMs适应医学图像分析。大量实验结果表明,ViP在两个具有挑战性的数据集上能够超越最先进的方法。

英文摘要:

Pre-trained large vision-language models (VLMs) like CLIP have revolutionized visual representation learning using natural language as supervisions, and demonstrated promising generalization ability. In this work, we propose ViP, a novel visual symptom-guided prompt learning framework for medical image analysis, which facilitates general knowledge transfer from CLIP. ViP consists of two key components: a visual symptom generator (VSG) and a dual-prompt network. Specifically, VSG aims to extract explicable visual symptoms from pre-trained large language models, while the dual-prompt network utilizes these visual symptoms to guide the training on two learnable prompt modules, i.e., context prompt and merge prompt, which effectively adapts our framework to medical image analysis via large VLMs. Extensive experimental results demonstrate that ViP can outperform state-of-the-art methods on two challenging datasets.
