DOI: 10.1016/j.irbm.2021.01.002

Abstract: Abstract Background Frequency band optimization improves the performance of common spatial pattern (CSP) in motor imagery (MI) tasks classification because MI-related electroencephalograms (EEGs) are highly frequency specific. Many variants of CSP algorithm divided the EEG… read more here.
