(a) Example network with |$K = 8$| groups and variance |$\sigma ^2 = 0.15$|. (b) Approximate marginal log-likelihood |$\mathcal {G}$| for each model as a function of |$K$|. (c) NMI between the fitted model and the true planted structure as a function of |$K$|. Each data series lines in (b,c) corresponds to a different choice of variance |$\sigma ^{2}$| in edge weights. Results are averaged over 20 trials and the error bars are the standard errors.
