Due to bugs in the MCMC sampler for the IHM, IDM, IRM, and IRMCB models, the inference and predictions for these models were not correct. We have therefore revised the sampler in the toolbox accompanying the article and rerun the experiments of Tables 1, 2, and 3.

The new results show that the BCD outperforms the existing methods for about half of the considered networks, but not for the majority, as we originally stated (see the updated Table 2). In terms of the number of components extracted by IRM and BCD, it still holds in general that the BCD extracts more clusters; however, the new results show that it is not the case for all the considered networks (see the updated Table 1).
