# Out-Of-Distribution Evaluation Set For The 2D Wave Equation
Out-of-distribution evaluation set for the 2d wave equation. The underlying PDE is the **wave equation**.
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](https://openreview.net/forum?id=22kNOkkokU)
- **ENMA: Tokenwise Autoregression for Generative Neural PDE Operators** — Armand Kassaï Koupaï, Lise Le Boudec, Louis Serrano, Patrick Gallinari. *NeurIPS 2025*.
