# plot_bcic_iv_2a_eegprep_cleaning

Pretrained artifacts for the Braindecode tutorial `examples/model_building/plot_bcic_iv_2a_eegprep_cleaning.py`.

These files are meant to be loaded by the tutorial so the docs can show stable predictions without retraining the model from scratch.

## Stored files

- `params.safetensors`: classifier parameters
- `history.json`: Skorch training history used by the tutorial plots
- `metadata.json`: summary metrics for the stored checkpoint

## Training data

The data that shaped these weights. The ids are the `datasets:` field of this card,
which braindecode reads into `model.card_data.datasets` when you call
`from_pretrained` (MOABB class names for MOABB datasets, OpenNeuro / NEMAR
accessions, Hub ids otherwise). `nm`/`on` ids are datasets on [NEMAR](https://nemar.org)
(`on` = NEMAR's copy of the OpenNeuro dataset with the same number). Rows marked
`private:` are data the authors did not release; they are not in `datasets:`.

| `datasets:` id | Dataset | Stage | Modality |
|---|---|---|---|
| [`nm000139`](https://nemar.org/dataset/nm000139) | [BCI Competition IV dataset 2a (4-class motor imagery, 9 subjects, 22 EEG channels), MOABB BNCI2014_001](https://moabb.neurotechx.com/docs/generated/moabb.datasets.BNCI2014_001.html) | training | EEG |

- Supervised trialwise EEGNeX after EEGPrep cleaning, subject 3 only. Gradient updates on session '0train' (MOABB session name); session '1test' is the skorch validation set and EarlyStopping(load_best=True) restores the epoch with the best validation loss, so the evaluation session selected the saved epoch (no gradient updates on it). Up to 100 epochs, patience 10. Preprocessing adds EEGPrep(resample_to=128, bad_window_max_bad_channels=None) before the 4-38 Hz filter.
