Dr. Chang-Dong Wang: Higher-Order Community Detection

Abstract: Higher-order community detection has gained an increasing amount of attention in the past few years. In this tutorial, we will first introduce the definition of higher-order community detection, the existing approaches, and the advantages compared with the lower-order community detection approaches. Then, we will introduce some recent approaches for higher-order community detection, including the edge enhancement approach for overcoming the hypergraph fragmentation issue, and the harmonic motif modularity approach for multi-layer network community detection. Finally, we will briefly make a discussion on the challenges to be addressed in the future work.
