| # Benchmarking Models on the Well |
|
|
| [The Well](https://github.com/PolymathicAI/the_well) is a 15TB dataset collection of physics simulations. This model is part of the models that have been benchmarked on the Well. |
|
|
|
|
| The models have been trained for a fixed time of 12 hours or up to 500 epochs, whichever happens first. The training was performed on a NVIDIA H100 96GB GPU. |
| In the time dimension, the context length was set to 4. The batch size was set to maximize the memory usage. We experiment with 5 different learning rates for each model on each dataset. |
| We use the model performing best on the validation set to report test set results. |
|
|
| The reported results are here to provide a simple baseline. **They should not be considered as state-of-the-art**. We hope that the community will build upon these results to develop better architectures for PDE surrogate modeling. |

| ## Loading the model from Hugging Face |
|
|
| To load the FNO model trained on the `acoustic_scattering_maze` of the Well, use the following commands. |
|
|
| ```python |
| from the_well.benchmark.models import FNO |
| |
| model = FNO.from_pretrained("polymathic-ai/FNO-acoustic_scattering_maze") |
| ``` |
