Out-Of-Distribution Evaluation Set For The 2D Gray-Scott Reaction-Diffusion Equation

Out-of-distribution evaluation set for the 2d gray-scott reaction-diffusion equation. The underlying PDE is the Gray-Scott reaction-diffusion.

This dataset contains out-of-distribution (OOD) samples for evaluating model generalization.

Data is stored in HDF5 (.h5) format.

Origin

This dataset was generated by Armand Kassai Koupaï and has been used in the following papers:

• ZEBRA: In-Context Generative Pretraining for Solving Parametric PDEs — Louis Serrano, Armand Kassaï Koupaï, Thomas X Wang, Pierre Erbacher, Patrick Gallinari. ICML 2025. OpenReview
