A Score-based Generative Solver for PDE-constrained Inverse Problems with Complex Priors
Yankun Hong, Harshit Bansal, Karen Veroy
In the field of inverse estimation for systems modeled by partial differential equations (PDEs), challenges arise when estimating high- (or even infinite-) dimensional parameters.…

Choosing observation operators to mitigate model error in Bayesian inverse problems
Nada CvetkoviÄ, Han Cheng Lie, Harshit Bansal +1
In statistical inference, a discrepancy between the parameter-to-observable map that generates the data and the parameter-to-observable map that is used for inference can lead to m…
