Conformal Prediction (CP) quantifies network uncertainty by building a small prediction set with a pre-defined probability that the correct class is within this set. In this study we tackle the problem of CP calibration based on a validation set with noisy labels. We introduce a conformal score that is robust to label noise. The noise-free conformal score is estimated using the noisy labeled data and the noise level. In the test phase the noise-free score is used to form the prediction set. We applied the proposed algorithm to several standard medical imaging classification datasets. We show that our method outperforms current methods by a large margin, in terms of the average size of the prediction set, while maintaining the required coverage.

通过在设定的概率内构建小的预测集合，拟合预测集合可量化网络不确定性。本研究针对带有噪声标签的校准问题，引入了一种对标签噪声具有鲁棒性的拟合得分。通过使用带有噪声标签的数据和噪声水平估算出无噪声的拟合得分，并在测试阶段使用该得分形成预测集合。我们将该算法应用于几个标准医学图像分类数据集，发现我们的方法在预测集合的平均大小方面明显优于当前方法，同时保持所需的覆盖率。
