MSE Values Between the Recovered and Ground-Truth SCV Cross-Correlations by aNy-Way ICA while Varying the Number of SCVs

MSE	2(a) Varying Number of SCVs (K)
	3	5	7	9	11
All*	2×10−4	5×10−4	6×10−4	2×10−2	6×10−3
Diag*	3×10−5	2×10−5	2×10−4	8×10−2	3×10−2
Off*	3×10−4	7×10−4	6×10−4	9×10−3	3×10−3

^*Note: ‘All’ denotes MSE of whole matrix, ‘Diag’ denotes MSE of diagonal blocks only, ‘Off’ denotes MSE of off-diagonal blocks only.
