Comparison of random field discretizations for high-resolution Bayesian parameter identification in finite element elasticity
Pieter Vanmechelen, Geert Lombaert, Giovanni Samaey
We compare three random field discretization strategies for probabilistic identification of spatially varying material parameters in high-resolution finite element models. These st…

Multilevel Markov Chain Monte Carlo with likelihood scaling for Bayesian inversion with high-resolution observations
Pieter Vanmechelen, Geert Lombaert, Giovanni Samaey
We propose a multilevel Markov chain Monte Carlo (MCMC) method for the Bayesian inference of random field parameters in PDEs using high-resolution data. Compared to existing multil…
