Adjusting protein graphs based on graph entropy. [PDF]

open access: yesBMC Bioinformatics, 2014
Measuring protein structural similarity attempts to establish a relationship of equivalence between polymer structures based on their conformations. In several recent studies, researchers have explored protein-graph remodeling, instead of looking a minimum superimposition for pairwise proteins.

Some Bounds of Weighted Entropies with Augmented Zagreb Index Edge Weights

open access: yesDiscrete Dynamics in Nature and Society, 2020
The graph entropy was proposed by Körner in the year 1973 when he was studying the problem of coding in information theory. The foundation of graph entropy is in information theory, but it was demonstrated to be firmly identified with some established ...

Asymptotic entropy of the Gibbs state of complex networks

open access: yesScientific Reports, 2021
In this work we study the entropy of the Gibbs state corresponding to a graph. The Gibbs state is obtained from the Laplacian, normalized Laplacian or adjacency matrices associated with a graph.

Graph Multi-Scale Permutation Entropy for Bearing Fault Diagnosis

open access: yesSensors, 2023
Bearing faults are one kind of primary failure in rotatory machines. To avoid economic loss and casualties, it is important to diagnose bearing faults accurately. Vibration-based monitoring technology is widely used to detect bearing faults. Graph signal

On the von Neumann entropy of graphs [PDF]

open access: yesJournal of Complex Networks, 2018
AbstractThe von Neumann entropy of a graph is a spectral complexity measure that has recently found applications in complex networks analysis and pattern recognition. Two variants of the von Neumann entropy exist based on the graph Laplacian and normalized graph Laplacian, respectively.

Explanatory Change Detection in Financial Markets by Graph-Based Entropy and Inter-Domain Linkage

open access: yesEntropy, 2022
In this study, we analyzed structural changes in financial markets under COVID-19 to support investors’ investment decisions. Because an explanation of these changes is necessary to respond appropriately to said changes and prepare for similar major ...

Symmetric Graphs with Respect to Graph Entropy

open access: yesThe Electronic Journal of Combinatorics, 2017
Let $F_G(P)$ be a functional defined on the set of all the probability distributions on the vertex set of a graph $G$. We say that $G$ is symmetric with respect to $F_G(P)$ if the uniform distribution on $V(G)$ maximizes $F_G(P)$. Using the combinatorial definition of the entropy of a graph in terms of its vertex packing polytope and the relationship ...
