CWT-BTD of the simulated EEG. RMSE is calculated between the time courses and spatial distributions of the simulated and reconstructed ictal source obtained from channel×time×frequency tensors with BTD for varying SNR values and varying the number of components R while the rank of the factor matrices L r is kept constant, or varying L r while R is kept constant. (a) CWT-BTD, R = 2, sinusoid source, RMSE in time course. (b) CWT-BTD, R = 2, sinusoid source, RMSE in spatial distribution. (c) CWT-BTD, L r = 2, sinusoid source, RMSE in time course. (d) CWT-BTD, L r = 2, sinusoid source, RMSE in spatial distribution. (e) CWT-BTD, R= 2, chirp source, RMSE in time course. (f) CWT-BTD, R = 2, chirp source, RMSE in spatial distribution. (g) CWT-BTD, L r = 2, chirp source, RMSE in time course. (h) CWT-BTD, L r = 2, chirp source, RMSE in spatial distribution. Top: scenario i (seizure with stationary frequency). Bottom: scenario ii (seizure with varying frequency).
