From: Critical analysis of (Quasi-)Surprise for community detection in complex networks
Effect of “potential” well in community detection. S1/S2, Sd/S2, Q1/Q2 and Q/Q2 as a function of the number of (the first-level) communities in the two-level networks. S1 (Q1), S2 (Q2) and Sd (Qd) denote the values of quality functions respectively for the first-level partition (without communities merging), the second-level partition (with communities merging), and the identified partition by different methods. Each measure is tested in three networks, denoted by I, II and III respectively. The parameters in the networks are set as follows: (A) Quasi-Surprise: pi = 1, pout1 = 0.19(I), 0.20(II) and 0.21(III), pout2 = 0.01. (B) Surprise: pi = 1, pout1 = 0.53(I), 0.54(II) and 0.55(III), pout2 = 0.1. (C) Significance: pi = 1, pout1 = 0.38(I), 0.40(II) and 0.42(III), pout2 = 0.2. (D) Modularity: pi = 1, pout1 = 0.03(I), 0.04(II) and 0.05(III), pout2 = 0.01.
