May enable real-time P300 EEG monitoring; hypothesis-generating and requires clinical validation before adoption.
The proposed ANPCA method effectively separates P300 components from EEG signals in real-time without down-sampling or averaging.
Turnip et al. (2011) studied Healthy subjects (EEG P300 detection) (n=7). Adaptive nonlinear principal component analysis (ANPCA) vs. NPCA, NSS-JD, JADE, and SOBI algorithms was evaluated on Separation performance index. The proposed adaptive nonlinear principal component analysis (ANPCA) algorithm successfully separated mixed source signals in real-time, demonstrating the shortest iteration time and a performance index of approximately 0.03.
