Figure 6.
(a) Probability of the “decreasing trend” pattern of length D with D = 2 … 7 (i.e., patterns 10, 210, 3210, …, 6543210) vs. the normalized pump current, I/Ith. For easy comparison, each probability is normalized to the value expected if the patterns are equally probable, 1/D!. (b) Normalised permutation entropy computed from the probabilities of the patterns of length D (with D = 2 … 7) vs. the normalized pump current. In both panels (a) and (b) regime transition points are clearly identified, which are consistent with the transition points that were detected in Fig. 5 with D = 3.
