131-数字病理基础模型的鲁棒性分析

02 Oct 2025

Description

这篇文章对数字病理学中的基础模型(FM)进行了系统性调查,重点关注其对非生物技术特征(如扫描仪或染色差异)的鲁棒性。作者提出了 PathoROB 基准,包含三个新指标(如鲁棒性指数)和四个多中心数据集,旨在量化和评估20个现有FM的鲁棒性缺陷。研究发现,FM鲁棒性不足会导致诊断下游任务中出现重大错误,即“巧手汉斯”学习问题,进而妨碍临床安全采用。该工作还提出了 FM 鲁棒化框架,包括图像空间、表示空间和训练鲁棒化方法,以减轻这些缺陷,并强调鲁棒性评估和集成必须成为未来 FM 设计的核心原则。References: Kömen J, de Jong E D, Hense J, et al.
