- Independent Component Analysis Applied in Biomedical Signal Processing
- The EEG is composed of electrical potentials arising from several sources. Each source (including separate neural clusters, blink artifact, or pulse artifact) projects a unique topography onto the scalp-'scalp maps'. These maps are mixed according to the principle of linear superposition. Independent component analysis ICA attempts to reverse the superposition...
