Comon independent component analysis
WebMay 4, 2014 · Independent component analysis (ICA) is closely related to principal component analysis (PCA). Whereas ICA finds a set of source variables that are mutually independent, PCA finds a set of variables that are mutually uncorrelated.

WebThe wavelet transform cannot be applied to remove external noises effectively. While the EEG signals can be collected by wearing a headset with sensors, some other unnoticed noise may be added. Compared with the wavelet transform, ICA is more suitable to remove non-random noise. The fundamental paper on the ICA was proposed by Comon[8].
