| # Models Pretrained on the Vlasiator Dataset for Ion-kinetic Plasma Emulation |
|
|
| The models have been produced using [spacecast](https://github.com/fmihpc/spacecast). The repository contains the following: |
| ``` |
| model_weights/ |
| ├── forecasts/ - Directory containing example forecasts for each run |
| ├── metrics/ - Evaluation metrics for each model variation in csv format |
| ├── plots/ - Evaluation figures showcasing RMSE, CRPS, SSR scores and qualitative results |
| ├── graph_efm_simple.ckpt - Pretrained Graph-EFM model with simple graph, 12 proc layers and 256 latent dim |
| ├── graph_efm_multiscale.ckpt - Pretrained Graph-EFM model with multiscale graph, 12 proc layers and 256 latent dim |
| ├── graph_efm_hierarchical.ckpt - Pretrained Graph-EFM model with hierarchical graph, 6 proc layers and 256 latent dim |
| ├── graph_fm_simple.ckpt - Pretrained Graph-FM model with simple graph, 12 proc layers and 256 latent dim |
| ├── graph_fm_multiscale.ckpt - Pretrained Graph-FM model with multiscale graph, 12 proc layers and 256 latent dim |
| └── graph_fm_hierarchical.ckpt - Pretrained Graph-FM model with hierarchical graph, 6 proc layers and 256 latent dim |
| ``` |
|
|
| In the `forecast` directory you will find 50 second forecasts for each of the for runs in [spacecast-data](https://huggingface.co/datasets/deinal/spacecast-data). The models used to produce these are `graph_efm_simple.ckpt` and `graph_fm_simple.ckpt`. Test set metrics are available in `metrics`. For a full evaluation including visualization of the example forecasts see the `plots` directory. |
