[Eeglablist] Multi class CSP and feature extraction

[Delorme, Arnaud]

Dear Abdul,

Not an expert in CSP but I believe the standard approach is to do pairwise CSP between your categories then use the CSP features as input to a multi-class classifier - such as softmax logistic regression. I think BCILAB can do that https://sccn.ucsd.edu/wiki/BCILAB

Found these papers if that helps

Best wishes, 

Arno
