When Attention Beats Fourier: Multi-Scale Transformers for PDE Solving on Irregular Domains
Brandon Yee, Pairie Koh, Jack Rodriguez +1
We study the problem of \emph{architecture selection} for deep learning models trained to solve partial differential equations (PDEs), asking when transformer-based architectures w…

PI-JEPA: Label-Free Surrogate Pretraining for Coupled Multiphysics Simulation via Operator-Split Latent Prediction
Brandon Yee, Pairie Koh
Reservoir simulation workflows face a fundamental data asymmetry: input parameter fields (geostatistical permeability realizations, porosity distributions) are free to generate in…
