Table 1 Computational complexity of CoM2, CCA, 2T-EMD and DWT algorithms

From: Removal of muscle artifact from EEG data: comparison between stochastic (ICA and CCA) and deterministic (EMD and wavelet-based) approaches

Algorithms	Numerical complexity (Flops)
CoM2	$B + min {12 I f_{4} (P) P^{2} + 2 I P^{3} + 3 M f_{4} (P) + M P^{2}, 13 I M P^{2} / 2} + I P^{2} Q / 2$
CCA	$5 M N^{2} + 5 M N + 19 N^{3} / 3$
2T-EMD	$\sum_{n = 1}^{N} \sum_{k = 1}^{K} \sum_{j = 1}^{J} (19 M + 17 f_{2 T} (n k, j)$
DWT	$4 (1 - 2^{- D}) N M O$
