Choosing the number of communities: Cargo. Left: the mean pairwise adjusted mutual information of the community-node membership across repeated decompositions. 1 is a perfectly stable assignment to communities; 0 is perfectly random. The shaded area corresponds to twice the standard error of the mean. Right: the mean normalised residual sum of squares error for repeated decompositions on the Cargo network against the number of components. The shaded area corresponds to twice the standard error of the mean above and below the line
