Afsari, BijanKrishnaprasad, Perinkulam S.We present a new scale-invariant cost function for non-orthogonal joint-diagonalization of a set of symmetric matrices with application to Independent Component Analysis (ICA). We derive two gradient minimization schemes to minimize this cost function. We also consider their performance in the context of an ICA algorithm based on non-orthogonal joint diagonalization.en-USOptimization on ManifoldsBlind Source SeparationTechnical Report
