The study introduces SPDNetψ to improve BCI decoding efficiency. It outperforms state-of-the-art DL architectures in MI decoding using only three electrodes. The augmentation procedure enhances classification performance and interpretability. GradCam++ visualization highlights the importance of off-diagonal terms in decision-making. Computational analysis shows longer time but lower environmental impact compared to other models.
