چکیده :
Event-related potential (ERP) extraction from ongoing electroencephalograph (EEG) and its enhancement is one of the long-established problems in EEG signal processing. Most of the previous studies have focused mainly on the ERP enhancement without considering the multi-dimensional structure of the signal. In order to take advantage of this property, we propose a tensor-based solution with trial-by-trial concatenated ERP data. Then we develop an algorithm based on low-rank Tucker decomposition to detect single trial ERP component with maximized signal to noise ratio (SNR). In other words, by using tensor algebra we consider both self-similarity in intra-trials and global correlation in spatial mode. Applicability of the algorithm is demonstrated in the context of P300 detection with synthetic data and the real EEG data collected from 8 subjects during a visual oddball experiment. Performance of the proposed method is evaluated with approximation errors and classification accuracy.
