Embedded Model Form Uncertainty Quantification with Measurement Noise for Bayesian Model Calibration
October 2024 • Daniel Andrés Arcones, Martin Weiser, Phaedon‐Stelios Koutsourelakis, Jörg F. Unger
A key factor in ensuring the accuracy of computer simulations that model physical systems is the proper calibration of their parameters based on real-world observations or experimental data. Inevitably, uncertainties arise, and Bayesian methods provide a robust framework for quantifying and propagating these uncertainties to model predictions. Nevertheless, Bayesian methods paired with inexact models usually produce predictions unable to represent the observed datapoints. Additionally, the quantified uncertainties…
