WebbHowever, how the two conditions are pathologically connected is not completely understood. Similar neurophysiological abnormalities have been reported in both DM and MDD, including elevated electroencephalographic (EEG) activity in low-frequency slow waves and increased latency and/or reduced amplitude of event-related potentials. Webb23 dec. 2024 · A Discriminative Slow Component Analysis algorithm is introduced to derive predictive features from EEG signals. Moreover, discrete wavelet transform is used to form epileptiform sub-waves that bring more predictive information. Finally, a cost-sensitive linear support vector machine is adopted to classify the preictal and interictal signals.
