Overall comparison between tensor decompositions of the simulated EEG. The performance of the different BSS approaches are compared using optimal model parameters, namely, R(CPD) = 4,R(CWT-BTD) = 2, L
(CWT-BTD) = 2 and R(H-BTD) = 3, L
(H-BTD) = 2 for a sinusoidal (a,b,c) or L
(H-BTD) = 6 for a chirp-like ictal source (d,e,f). Top: scenario i (seizure with stationary frequency). Bottom: scenario ii (seizure with varying frequency).
