Figure 4

(a) Contour map of log(Einter) in the (σ, λ) parameter space with Inline graphic (class III in the intra- and inter-layer dynamics) and m = 50 links removed from Inline graphic. The black contour line corresponds to the isoline where the MLE changes its sign from positive to negative. Color code is shown in the lateral bar. (b) MLE vs. σ for fixed λ = 0.12 (corresponding to the dotted line in the left panel) where the 50 links with largest (m+ = 50, Inline graphic) and lowest (m = 50, ●) betweenness are removed from Inline graphic. The identical case Inline graphic (*) is also plotted for comparison. (c) Averaged intra-layer error difference Inline graphic for the same parameter values as in (b). In all panels, the two layers are ER of N = 500 Rössler oscillators and 〈k〉 = 8. Each point is an average over 5 realizations.
