The TF signals of two classes (NS and PS) are simultaneously decomposed using the JLNMF algorithm. a The shared TF bases between PS and NS classes (i.e., W j ) and the PS-specific TF bases (W spike). b Two EEG recording samples (top with two spikes and bottom with no spikes). c The PS-specific reconstructed TF data. The red arrows indicate epileptic spikes
