Fast Incremental von Neumann Graph Entropy Computation: Theory, Algorithm, and Applications

ICML 2019oral

The von Neumann graph entropy (VNGE) facilitates measurement of information divergence and distance between graphs in a graph sequence. It has been successfully applied to various learning tasks driven by network-based data. While effective, VNGE is computationally demanding as it requires the full…

Latent Heterogeneous Multilayer Community Detection

ICASSP 2019accepted

We propose a method for simultaneously detecting shared and unshared communities in heterogeneous multilayer weighted and undirected networks. The multilayer network is assumed to follow a generative probabilistic model that takes into account the similarities and dissimilarities between the communi…

First-Order Bifurcation Detection for Dynamic Complex Networks

ICASSP 2018accepted

In this paper, we explore how network centrality and network entropy can be used to identify a bifurcation network event. A bifurcation often occurs when a network undergoes a qualitative change in its structure as a response to internal changes or external signals. In this paper, we show that netwo…
