Comments on "CuBICA: Independent Component Analysis by Simultaneous third- and Fourth-Order Cumulant Diagonalization

Source separation based on joint diagonalization of cumulant matrices or tensors has led now to classical algorithms. In a previous paper by Blaschke and Wiskott, an algorithm based on the above principle is proposed. It combines third- and fourth-order cumulants and it is claimed to possess interesting properties. This comment has two objectives. We point out imprecisions of statement and we give additional references of closely related works, some of them presenting identical issues
