A distance metric between directed weighted graphs [PDF]
52nd IEEE Conference on Decision and Control, 2013 Directed weighted graphs are increasingly used to model complex systems and interactions, such as networks of interconnected physical or biological subsystems. The analysis of these graphs often requires some form of dissimilarity, or distance measure to compare graphs.

On the Eigenvalues of Weighted Directed Graphs [PDF]
Complex Analysis and Operator Theory, 2016 This paper deals with spectral graph theory issues related to questions of monotonicity and comparison of eigenvalues. We consider finite directed graphs with non symmetric edge weights and we introduce a special self-adjoint operator as the sum of two non self-adjoint Laplacians.

Community mining on dynamic weighted directed graphs [PDF]
Proceedings of the 1st ACM international workshop on Complex networks meet information & knowledge management, 2009 This paper focuses on community mining including community discovery and change-point detection on dynamic weighted directed graphs(DWDG). Real networks such as e-mail, co-author and financial networks can be modeled as DWDG. Community mining on DWDG has not been studied thoroughly, although that on static(or dynamic undirected unweighted)graphs has ...

Directional graph weight prediction for image compression [PDF]
2017 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2017 Graph-based models have recently attracted attention for their potential to enhance transform coding image compression thanks to their capability to efficiently represent discontinuities. Graph transform gets closer to the optimal KLT by using weights that represent inter-pixel correlations but the extra cost to provide such weights can overwhelm the ...

Nonlinear Merging Consensus for Multi-Agent Systems on Directed and Weighted Signed Graph
IEEE Access, 2020 This paper settles the nonlinear merging consensus for multi-agent systems on a directed and weighted signed network. A novel nonlinear merging control protocol is proposed to drive the states of all agents to arrive at the same state.

Applied Network Science, 2019 Many graph mining tasks can be viewed as classification problems on high dimensional data. Within this class we consider the issue of discovering core-periphery structure, which has wide applications in the economic and social sciences.

Graph theory applications in congenital heart disease
Scientific Reports, 2023 Graph theory can be used to address problems with complex network structures. Congenital heart diseases (CHDs) involve complex abnormal connections between chambers, vessels, and organs.
