Hello, my name is Corina and I am a student in terminal year. Can you please, tell me if you used an algorithm presented in an article for this implementation? I am referring to the imagined movement code.

wmvanvliet commented 2 years ago

The algorithm is called Common Spatial Patterns (CSP). Here is one of the first articles describing its use in BCI: https://ieeexplore.ieee.org/document/895946

Corinamar commented 2 years ago

Thank you so much! Can you please tell me if the code is only for one signal or if it is for the whole dataset? I am a beginner.

wmvanvliet commented 2 years ago

Could you explain a bit more about what you mean by "one signal" and "whole dataset"?

Corinamar commented 2 years ago

Sure. The BCI Competition IV has 10 recordings of EEG signals. I would like to know if you used only one recording or if you used all 10 recordings, especially for LDA classification. Thank you!

wmvanvliet commented 2 years ago

ah, now I understand, thank you. It only uses a single recording.

Corinamar commented 2 years ago

Ok. Thank you so much!

Corinamar commented 2 years ago

Hello, I am sorry to bother you again, but could you explain why the window size is 0.5-2.5 seconds?

wmvanvliet commented 2 years ago

Because at that time, the event-related desynchronization (ERD) is most prominent in the EEG signal.

Corinamar commented 2 years ago

Thank you, I really appreciate it and I really am sorry for bothering you.
