Characterizing and Utilizing the Interplay Between Core and Truss Decompositions
Penghang Liu, A. Erdem Sarıyüce
Finding the dense regions in a graph is an important problem in network analysis. Core decomposition and truss decomposition address this problem from two different perspectives. T…
Temporal Network Motifs: Models, Limitations, Evaluation
Penghang Liu, Valerio Guarrasi, A. Erdem Sarıyüce
Investigating the frequency and distribution of small subgraphs with a few nodes/edges, i.e., motifs, is an effective analysis method for static networks. Motif-driven analysis is…
