Abstract: Highlights•Full-epoch decoding models achieve higher accuracy than sliding window models.•Temporal, spatial, and spectral patterns are extracted from full-epoch models.•A single multiclass model can be used for pairwise decoding without retraining.•Learning the dimensionality reduction of features for decoding improves on PCA.
