Deeper Exploiting Graph Structure Information by Discrete Ricci Curvature in a Graph Transformer

open access: yesEntropy, 2023
Graph-structured data, operating as an abstraction of data containing nodes and interactions between nodes, is pervasive in the real world. There are numerous ways dedicated to extract graph structure information explicitly or implicitly, but whether it ...

Oriented gain graphs, line graphs and eigenvalues [PDF]

open access: yesLinear Algebra and its Applications, 2016
A theory of orientation on gain graphs (voltage graphs) is developed to generalize the notion of orientation on graphs and signed graphs. Using this orientation scheme, the line graph of a gain graph is studied. For a particular family of gain graphs with complex units, matrix properties are established.

Matroids of Gain Graphs in Applied Discrete Geometry [PDF]

open access: greenTransactions of the American Mathematical Society, 2012
A Γ \Gamma -gain graph is a graph whose oriented edges are labeled invertibly from a group Γ \Gamma . Zaslavsky proposed two matroids associated with Γ \Gamma -gain graphs, called frame matroids and lift matroids, and investigated linear representations of them.

Bayesian graph edit distance [PDF]

open access: yes, 2000
This paper describes a novel framework for comparing and matching corrupted relational graphs. The paper develops the idea of edit-distance originally introduced for graph-matching by Sanfeliu and Fu [1].

The graph grabbing game on {0,1}-weighted graphs

open access: yesResults in Applied Mathematics, 2019
The graph grabbing game is a two-player game on a weighted connected graph in which two players, Alice and Bob, alternatively remove non-cut vertices one by one to gain the weights on them.

Independence ratio and random eigenvectors in transitive graphs [PDF]

open access: yes, 2015
A theorem of Hoffman gives an upper bound on the independence ratio of regular graphs in terms of the minimum $\lambda_{\min}$ of the spectrum of the adjacency matrix.

A stochastic model for the evolution of the web allowing link deletion [PDF]

open access: yes, 2004
Recently several authors have proposed stochastic evolutionary models for the growth of the web graph and other networks that give rise to power-law distributions.

Feature-Enhanced Latent Summarization Model of Heterogeneous Network [PDF]

open access: yesJisuanji kexue yu tansuo, 2022
With the rapid growth of network data, large-scale heterogeneous network data storage and network repre-sentation have become hot research topics. This paper proposes two different tasks, generating graph summarization and generating node representations
