English(EN) Let Confidence Change, Not the Prediction: Prediction-Preserving Repair for Post-hoc Calibration

新的CORD方法在AI模型校准过程中保持了top-1预测

作者 PulseAugur 编辑部 · [1 个来源] ·

一种名为CORD（Calibrator-Output Repair for Top-1 Decision Preservation，校准器输出修复以保持top-1决策）的新方法已被开发出来，用于解决机器学习模型的后置校准问题。与可能改变top-1预测的先前方法不同，CORD在纠正置信度分数的同时，确保原始预测保持不变。这是通过修复校准后的概率向量以保持初始的top-1决策来实现的。在CIFAR-10/100和ImageNet-1K等数据集上的实验表明，CORD成功地将Top-1预测变化率（TPCR）保持在零，并改进了期望校准误差（ECE）和负对数似然（NLL）等指标。 AI

影响 该方法可以在不牺牲预测准确性的情况下提高AI模型置信度分数的可靠性。

    让置信度改变，而非预测：事后校准的预测保持修复

    arXiv:2609.01072v1 Announce Type: new Abstract: Post-hoc calibration corrects reported confidence, yet a multiclass calibrator can also change the associated top-1 prediction. Accuracy captures only the net effect of these changes on correctness, not how often predictions change;…
