研究人员引入了一个名为序数交叉熵（OCE）的新框架，旨在改进具有固有序数结构的医疗应用深度学习模型。与将所有错误分类同等对待的传统交叉熵损失函数不同，OCE 包含一个序数成本矩阵，以考虑不同序数类别之间错误的严重程度差异。这种方法旨在提供更平滑的优化动态和更好的序数一致性，与现有的最先进的序数方法相比，可以降低预测误差成本并提高校准。 AI
影响 通过更好地处理序数风险，引入了一种新颖的损失函数，以提高医疗人工智能应用的准确性和校准。

In many prediction problems in medical applications, target labels exhibit an inherent ordinal structure, where class ordering reflects clinically meaningful severity levels. The cost associated with misclassification is often non-uniform and asymmetric, as errors between distant…
