I want to add a program

[hljuniversity]

Hello, thank you for sharing the code，I added a piece of de-noising code to the ATCNet model, which reduced the accuracy of the verification set. I don't understand why. Do you understand?

Hi, It depends on which method you used. Some key features may be lost during the denoising process. In deep learning (DL), noise may not be an issue. DL can learn very well from noisy data. Also, adding noise to the EEG data is one way to augment the data and help the model to generalize well. I haven't worked with noise removal in the EEG data; However, you may refer to the following review article which discusses the effect of pre-processing on MI-EEG data (including denoising) for DL-based techniques.
