From principal to independent component analysis of brain signals
Ricardo Vigário · 2005
The purpose of this paper is to introduce the attendee/reader of the special session on component analysis and brain signals to, or refresh the concepts of the classical principal component analysis (PCA) and the more recent independent component analysis (ICA). Some motivations for their use in the context of electromagnetic brain signal processing are given. An illustrative example in event related studies is as well provided.
