"NettetWhen aggregating, a single cluster may then be represented by several nodes (which are the subclusters identified in the refinement). The Leiden algorithm provides several guarantees. The Leiden algorithm is typically iterated: the output of one iteration is used as the input for the next iteration. " - Leiden graph-clustering
