English(EN) Conviction Without Evidence: Verdict Stability Is Independent of Visual Grounding in Medical Vision--Language Models

医学AI模型在无视觉证据的情况下捏造诊断

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-27 04:00

一篇题为“无证据的定罪：医学视觉-语言模型中的判断稳定性与视觉基础无关”的新研究论文探讨了视觉-语言模型在医学诊断中的可靠性。研究发现，即使在没有诊断图像的情况下，这些模型仅依靠临床文本也能得出正确的诊断。此外，研究表明，当图像缺失时，模型的信心不会下降，这表明可能缺乏真正的视觉基础。 AI

影响凸显了医学AI中潜在的不可靠性，因为模型可能在没有真正视觉基础的情况下捏造诊断。

无证据定罪：医疗视觉-语言模型中的判决稳定性与视觉基础无关

arXiv:2610.34520v1 Announce Type: cross Abstract: Vision--language models applied to medical question answering can reach correct diagnoses without using the diagnostic image, inferring instead from the clinical vignette. We ask whether this is visible in how \emph{firmly} a mode…
