This arises because of the penalties on the block memberships and support that increase significantly and exceeds the gain on the ELBO and the diminution of the connectivity parameters. An idea to tackle this problem could be to suppose that the block memberships for network $m$ are themselves the realizations of random variables and thus introduce sort of a mixed effect model. \paragraph{Comparison to other graphs clustering methods} Recent work have been comparing colSBM~\parencite{chabert-liddellLearningCommonStructures2024a} and graphclust~\parencite{rebafkaModelbasedClusteringMultiple2023} assessing various capabilities of the models and particularly focusing on networks clustering. We will reproduce and adapt the analysis to test other simulation settings that were not considered in this work. \section*{Thank you for reading this work}
