Hybrid Iterative Ensemble Smoother for History Matching of Hierarchical Models
(Peer reviewed; Journal article, 2022)The choice of a 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 initial ensemble are generated from the same ... -
p-Kernel Stein Variational Gradient Descent for Data Assimilation and History Matching
(Journal article; Peer reviewed, 2021)A Bayesian method of inference known as “Stein variational gradient descent” was recently implemented for data assimilation problems, under the heading of “mapping particle filter”. In this manuscript, the algorithm is ...
