Hybrid iterative ensemble smoother for history matching of hierarchical models
Dean S. Oliver
The choice of the prior model can have a large impact on the ability to assimilate data. In standard applications of ensemble-based data assimilation, all realizations in the initi…
Randomized maximum likelihood based posterior sampling
Yuming Ba, Jana de Wiljes, Dean S. Oliver +1
Minimization of a stochastic cost function is commonly used for approximate sampling in high-dimensional Bayesian inverse problems with Gaussian prior distributions and multimodal…
Truncation map estimation based on bivariate probabilities and validation for the truncated plurigaussian model
Alina Astrakova, Dean S. Oliver, Christian Lantuéjoul
The truncated plurigaussian model is often used to simulate the spatial distribution of random categorical variables such as geological facies. The problems addressed in this paper…
Metropolized Randomized Maximum Likelihood for sampling from multimodal distributions
Dean S. Oliver
This article describes a method for using optimization to derive efficient independent transition functions for Markov chain Monte Carlo simulations. Our interest is in sampling fr…
