新框架通过控制预测误差改进计算机模型校准

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-23 04:00

研究人员开发了一种新颖的两层计算机模型校准框架，直接针对预测误差。该方法利用条件流匹配模型学习校准参数的摊销后验，该模型在扰动模拟器输出上进行训练。然后，一个保形风险控制层将后验样本排列成嵌套候选集，以确保规定的失覆盖率。该框架在合成基准测试中证明了其有效性，产生的区间比传统方法窄约20%，且失覆盖率接近标称值，并在将SEIR模型校准到现实世界疫情数据时显示出潜力，揭示了模型的局限性。 AI

影响这项研究通过改进校准技术，有望在各个科学领域带来更可靠的预测模型。

Prediction Uncertainty Controlled Computer Model Calibration

arXiv:2610.31163v1 Announce Type: cross Abstract: Computer-model calibration is usually undertaken in service of prediction, yet neither Bayesian Kennedy-O'Hagan (KOH) calibration nor amortized simulation-based inference is built to control the predictive error of the calibrated …
