I downloaded data BCI-IV-2a from the official website. Referring to your paper, I used the python MNE package for preprocessing. Running your Conformerd code on GitHub without filtering has an average accuracy of only 68.98%; If you add filtering, the accuracy is lower.May I ask why this is?
There are many possible reasons such as pre-processing (segmentation, band-pass filter, z-score, etc), data augmentation, model parameters. I suggest to recheck the details.
