Abstract :
We develop a technique for Blind Source Separation based on simultaneous diagonalization of (linear combinations of) third-order tensor "slices" of the fourth-order cumulant. It will be shown that, in a Jacobi-type iteration scheme, the computation of an elementary rotation can be reformulated in terms of a simultaneous matrix diagonalization.
