Latent heterogeneous multilayer community detection
Hafiz Tiomoko Ali, Sijia Liu, Yasin Yilmaz +3
We propose a method for simultaneously detecting shared and unshared communities in heterogeneous multilayer weighted and undirected networks. The multilayer network is assumed to…
AMOS: An Automated Model Order Selection Algorithm for Spectral Graph Clustering
Pin-Yu Chen, Thibaut Gensollen, Alfred O. Hero
One of the longstanding problems in spectral graph clustering (SGC) is the so-called model order selection problem: automated selection of the correct number of clusters. This is e…
Identifying Influential Links for Event Propagation on Twitter: A Network of Networks Approach
Pin-Yu Chen, Chun-Chen Tu, Pai-Shun Ting +3
Patterns of event propagation in online social networks provide novel insights on the modeling and analysis of information dissemination over networks and physical systems. This pa…
Phase Transitions and a Model Order Selection Criterion for Spectral Graph Clustering
Pin-Yu Chen, Alfred O. Hero
One of the longstanding open problems in spectral graph clustering (SGC) is the so-called model order selection problem: automated selection of the correct number of clusters. This…
Multi-centrality Graph Spectral Decompositions and their Application to Cyber Intrusion Detection
Pin-Yu Chen, Sutanay Choudhury, Alfred O. Hero
Many modern datasets can be represented as graphs and hence spectral decompositions such as graph principal component analysis (PCA) can be useful. Distinct from previous graph dec…
Incremental Method for Spectral Clustering of Increasing Orders
Pin-Yu Chen, Baichuan Zhang, Mohammad Al Hasan +1
The smallest eigenvalues and the associated eigenvectors (i.e., eigenpairs) of a graph Laplacian matrix have been widely used for spectral clustering and community detection. Howev…
