“…As one of the most attractive solutions for the blind source separation (BSS) problem, independent component analysis (ICA) has a strong practical background and wide applications in multiway data analysis such as biomedicine [1], image processing [2], telecommunications [3], geophysical research field [4,5], and physics of musical instruments [6,7], because it is a combination of informationism, optimal theory, probability, matrix theory, and mathematical statistics. Indeed, several papers recently have been written in which standard linear ICA, for instantaneous mixtures, was successfully applied to many natural environments as explosion-quakes and tremor at Stromboli and Erebus volcanoes [8,9], to study acoustical and mechanical vibrational field in organ pipe [10].…”
