Pre- and post-processing in quantum-computational hydrologic inverse analysis
John K. Golden, Daniel O'Malley
It was recently shown that certain subsurface hydrological inverse problems -- here framed as determining the composition of an aquifer from pressure readings -- can be solved on a…
Learning to regularize with a variational autoencoder for hydrologic inverse analysis
Daniel O'Malley, John K. Golden, Velimir V. Vesselinov
Inverse problems often involve matching observational data using a physical model that takes a large number of parameters as input. These problems tend to be under-constrained and…
Large-scale Inversion of Subsurface Flow Using Discrete Adjoint Method
Shu Wang, Satish Karra, Daniel O'Malley
Sensitivity analysis plays an important role in searching for constitutive parameters (e.g. permeability) subsurface flow simulations. The mathematics behind is to solve a dynamic…
