AI总结:

本文提出一种基于可解释原型部分模型与分割掩码、用户精炼原型引导监督的黑色素瘤诊断方法,在无专家监督下性能与泛化优于不可解释模型。

摘要:

通过皮肤镜图像分析进行皮肤癌检测是一项关键任务。然而,现有用于此目的的模型往往缺乏可解释性和可靠性,由于其黑箱特性,引起了医生的担忧。在本文中,我们提出了一种使用可解释的原型部分模型进行黑色素瘤诊断的新方法。我们引入了基于非专家反馈的引导监督,通过结合:1)使用分割网络自动获取的二进制掩码;2)用户精炼的原型。这两条不同的信息通路旨在确保学习到的原型对应于皮肤病变内的相关区域,排除其边界之外的混杂因素。实验结果表明,即使没有专家监督,我们的方法在性能和泛化能力上也优于不可解释的模型。

英文摘要:

Skin cancer detection through dermoscopy image analysis is a critical task. However, existing models used for this purpose often lack interpretability and reliability, raising the concern of physicians due to their black-box nature. In this paper, we propose a novel approach for the diagnosis of melanoma using an interpretable prototypical-part model. We introduce a guided supervision based on non-expert feedback through the incorporation of: 1) binary masks, obtained automatically using a segmentation network; and 2) user-refined prototypes. These two distinct information pathways aim to ensure that the learned prototypes correspond to relevant areas within the skin lesion, excluding confounding factors beyond its boundaries. Experimental results demonstrate that, even without expert supervision, our approach achieves superior performance and generalization compared to non-interpretable models.
