WebJan 8, 2024 · Here, we study the use of multiscale community detection applied to similarity graphs extracted from data for the purpose of unsupervised data clustering. The basic idea of graph-based clustering is shown schematically in Fig. 1. Specifically, we focus on the problem of assessing how to construct graphs that appropriately capture the structure ...
