CPD of the simulated EEG. RMSE was calculated between the time courses and spatial distributions of the simulated and reconstructed ictal source obtained from channel×time×frequency tensors with CPD for various number of extracted components (R) and various SNR values. (a) CPD, sinusoid source, RMSE in time course. (b) CPD, sinusoid source, RMSE in spatial distribution. (c) CPD, chirp source, RMSE in time course. (d) CPD, chirp source, RMSE in spatial distribution. Top: scenario i (seizure with stationary frequency). Bottom: scenario ii (seizure with varying frequency).
