1D Combined Equation Dataset

1d combined equation dataset. The underlying PDE is the combined equation (varying PDE coefficients).

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
  • ENMA: Tokenwise Autoregression for Generative Neural PDE Operators — Armand Kassaï Koupaï, Lise Le Boudec, Louis Serrano, Patrick Gallinari. NeurIPS 2025.
