AI总结:

本文通过引入鲁棒性损失,提升了计算病理学基础模型的鲁棒性,提高了分类准确率,且无需重新训练基础模型,从而更适用于实际临床应用。

摘要:

计算病理学的基础模型预计能促进开发高性能、可推广的深度学习系统。然而,除了生物相关特征外,当前基础模型还捕捉了预分析和扫描特定的变异,这些变异会偏移下游任务特定模型在这些特征上训练时的预测。本文表明,在下游模型训练中引入新的鲁棒性损失可以减少对技术变异的敏感性。使用包含27,042张全玻片图像和6,155名患者的数据集,训练了数千个模型,基于八个知名计算病理学基础模型的特征。除了显著的鲁棒性提升外,我们的方法通过关注生物相关特征提高了分类准确率。它在不重新训练基础模型的情况下缓解了计算病理学基础模型的鲁棒性限制,从而开发出更适合实际临床应用的模型。

英文摘要:

Foundation models for computational pathology are expected to facilitate the development of high-performing, generalisable deep learning systems. However, in addition to biologically relevant features, current foundation models also capture pre-analytic and scanner-specific variation that bias the predictions made by downstream task-specific models trained on these features. Here we show that introducing novel robustness losses during downstream model training reduces sensitivity to technical variability. A purpose-designed comprehensive experimentation setup with 27,042 whole-slide images from 6,155 patients is used to train thousands of models from the features of eight well-known foundation models for computational pathology. In addition to a substantial improvement in robustness, our approach improves classification accuracy by focusing on biologically relevant features. It mitigates robustness limitations of foundation models for computational pathology without retraining the foundation models themselves, enabling development of models that are more suitable in real-world clinical use.
