New framework improves computer model calibration by controlling predictive error

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel two-layer framework for computer model calibration that directly targets predictive error. This method utilizes a conditional flow-matching model to learn an amortized posterior for calibration parameters, trained on perturbed simulator outputs. A conformal risk control layer then arranges posterior draws into nested candidate sets to ensure prescribed miscoverage levels. The framework demonstrated effectiveness in a synthetic benchmark, producing bands approximately 20% narrower than traditional methods with near-nominal miscoverage, and also showed promise in calibrating an SEIR model to real-world epidemic data, revealing model limitations.

    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 …
