Green-Routed Neural Operators: Physics Determines Where the Network Reads

We identify a mismatch between the physical role of transport fields in many PDEs and their usual role in neural operators: PDEs use them to select read coordinates, whereas neural operators typically treat them only as input values. We address this mismatch with the Green-Routed Neural Operator (GRNO), which uses the...

RD-JEPA: Predictive latent pretraining for few-trajectory transfer across reaction--diffusion equations

RD-JEPA, a joint-embedding predictive architecture for self-supervised pretraining on reaction-diffusion trajectories, indicates that prediction of future-state representations can support data-efficient adaptation across related reaction-diffusion systems.
