A Bayesian Framework for Extrapolative Emulation of Spatially Gridded Simulation Data
Kelly R. Moran, Ky Potter, Chris Danly +1
We propose a Bayesian emulator for extrapolating spatially gridded simulation output across resolution. The method treats each pixel as following a nonlinear resolution-response cu…
