Abstract: Single-trial electroencephalogram (EEG) data are analyzed with similarity measure. Time–frequency representation is constructed from EEG signals. It is then weighted with t-statistics. Finally, the test data are discriminated with similarity measure. Compared with non-weighted version, the experimental results indicate that the proposed method obtains better results in classification accuracy.

Keywords: Electroencephalography (EEG), similarity measure, time–frequency representation, brain–computer interface (BCI)
