Better and Easier Clustering: Practice Previous Work: Practical Justification Finding overlapping clusters for public graphs(Andersen, Gleich, M., ACM WSDM 2012) – Ran on graphs with up to 8 million nodes. – Compared with Metis and GRACLUS Much better conductance. Clustering a Youtube video subgraph (Lu, Gargi, M., Yoon, ICWSM 2011) – Clustered graphs with 120M nodes and 2B edges in 5 hours.
