- hyperspy.misc.machine_learning.tools.amari(W, A)
Calculate the Amari distance between two non-singular matrices.
Convenient for checking convergence in ICA algorithms (See [Moreau1998] and [Bach2002]).
W (array-like) – The two matrices to measure.
A (array-like) – The two matrices to measure.
Amari distance between W and A.
