For many centuries ideas now embodied in graph theory have been implicit in lay discussions of networks. The explicit linking of graph theory and network analysis began only in 1953 and has been rediscovered many times since. Analysts have taken from graph theory mainly concepts and terminology; ...

2) shared weights reduce 2 ural science (physical systems [3], [4] and protein-protein the computational cost compared with traditional spectral 1 interaction networks [5]), knowledge graphs [6] and many graph theory [10]. 3) multi-layer structure is the key to deal 8 other research ...
In order to improve the safety of network and grasp the safety situation of network correctly, the graph theory and neutral network was combined to have safety analysis for the network securityFirstly, the relating studies was summarized; and then basic theory of the graph theory model of neutral...
Structural Graph Theory Calculator StructuralGT is designed as an easy-to-use python-based application for applying graph theory (GT) analysis to structural networks of a wide variety of material systems. This application converts digital images of nano-/micro-/macro-scale structures into a graph ...
Data science and machine learning have become an integral part of natural sciences, discussed as the fourth pillar in science, next to experiment, theory, and simulation1. Machine learning methods are increasingly applied in all steps of the materials development cycle, from finding initial candidate...
We propose a new type of supervised visual machine learning classifier, GSNAc, based on graph theory and social network analysis techniques. In a previous study, we employed social network analysis techniques and introduced a novel classification model (called Social Network Analysis-based Classifier—...
