PosteriorBench: From Point Estimates to Posterior Matching in Evaluating Generative Inverse Solvers
Jiachen Yao, Zi-Siang Hsu, Xi Deng +5
Generative models are increasingly used to solve scientific inverse problems, but existing evaluations still focus primarily on whether a method can produce a single plausible reco…
Function-Space Decoupled Diffusion for Forward and Inverse Modeling in Carbon Capture and Storage
Xin Ju, Jiachen Yao, Anima Anandkumar +2
Accurate characterization of subsurface flow is critical for Carbon Capture and Storage (CCS) but remains challenged by the ill-posed nature of inverse problems with sparse observa…
Adaptive Physics Transformer with Fused Global-Local Attention for Subsurface Energy Systems
Xin Ju, Nok Hei, Fung +6
The Earth's subsurface is a cornerstone of modern society, providing essential energy resources like hydrocarbons, geothermal, and minerals while serving as the primary reservoir f…
Learning Pore-scale Multi-phase Flow from Experimental Data with Graph Neural Network
Yuxuan Gu, Catherine Spurin, Gege Wen
Understanding the process of multiphase fluid flow through porous media is crucial for many climate change mitigation technologies, including CO geological storage, hydrogen st…
