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…
Sequential Defense Against Random and Intentional Attacks in Complex Networks
Pin-Yu Chen, Shin-Ming Cheng
Network robustness against attacks is one of the most fundamental researches in network science as it is closely associated with the reliability and functionality of various networ…
Universal Phase Transition in Community Detectability under a Stochastic Block Model
Pin-Yu Chen, Alfred O. Hero
We prove the existence of an asymptotic phase transition threshold on community detectability for the spectral modularity method [M. E. J. Newman, Phys. Rev. E 74, 036104 (2006) an…
Node Removal Vulnerability of the Largest Component of a Network
Pin-Yu Chen, Alfred O. Hero
The connectivity structure of a network can be very sensitive to removal of certain nodes in the network. In this paper, we study the sensitivity of the largest component size to n…
