plot_bcic_iv_2a_moabb_cropped

Pretrained artifacts for the Braindecode tutorial examples/model_building/plot_bcic_iv_2a_moabb_cropped.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 (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	BCI Competition IV dataset 2a (4-class motor imagery, 9 subjects, 22 EEG channels), MOABB BNCI2014_001	training	EEG

• Supervised cropped-decoding ShallowFBCSPNet (dense prediction, 1000-sample windows), 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. Same preprocessing as the trialwise tutorial.
