DCG Construction at a given frequency band. Each wavelet coefficient matrix of IED or non-IED segment m (m = 1, …, L^l), $S_{m}^{l} \in R^{T_{m}^{l} \times N}$ provides one symmetric N × N coupling measure matrix, $Γ_{m}^{l}$ . Each $Γ_{m}^{l}$ builds the mth row of the matrix C^l ∈ , which contains all of the information concerning couplings between all of the possible connections at each frequency level. The DCG connections are identified by comparing C¹ and C², using multiple testing.
