Rythm isolation before ICA ?
Posted: 02 Nov 2016, 06:38
can rythm isolation ( mu and beta ) be done on EEG.data before running ICA and the resulting activation matrix ( obtained directly as a matrix in eeglab ) be used for feature extraction ? However , the following paper https://arxiv.org/ftp/arxiv/papers/1312/1312.2877.pdf has done it differently . It performed ICA first and then performed rythm isolation which changes only the EEG.data ( say EEG.data_new) and then asks to perform weights*sphere*(EEG.data_new-meandata) . Which one is correct ? Thank you .
