ModaLens 审计显示医学视觉语言模型更依赖文本而非图像

研究人员开发了 ModaLens,一种用于衡量医学领域视觉语言模型(VLM)敏感性的新审计方法。使用 MIMIC-CXR 数据上的 MedGemma-27B 模型,研究发现,当放射学报告可用时,模型的图像数据依赖性会显著降低。具体而言,当报告存在时,模型的答案仅改变 4.26%,而当报告不存在时则改变 20.94%,这表明文本报告严重影响了模型的输出,可能以牺牲视觉解释为代价。 AI

影响 强调了医学视觉语言模型可能过度依赖文本,表明需要改进临床应用中的图像关联性。

    ModaLens:衡量报告条件医学视觉语言模型中的图像敏感性

    arXiv:2609.15635v1 Announce Type: cross Abstract: A radiology report can already answer a clinical question, so it is hard to tell whether a vision-language model also uses the image. ModaLens, a paired image-swap audit, measures how report availability changes image sensitivity:…

    ModaLens:衡量报告条件医学视觉语言模型中的图像敏感性

    A paired image-swap audit reveals that report availability substantially reduces vision-language model sensitivity to image changes in radiology question answering.
