Further study of eccentricity based indices for benzenoid hourglass network

open access: yesHeliyon, 2023
Topological Indices are the mathematical estimate related to atomic graph that corresponds biological structure with several real properties and chemical activities. These indices are invariant of graph under graph isomorphism.

Spectrally Robust Graph Isomorphism [PDF]

open access: yes, 2018
We initiate the study of spectral generalizations of the graph isomorphism problem. b) The Spectral Graph Dominance (SGD) problem: On input of two graphs G and H does there exist a permutation pi such that G preceq pi(H)?

A Graph Isomorphism Network with Weighted Multiple Aggregators for Speech Emotion Recognition

open access: yes, 2022
Speech emotion recognition (SER) is an essential part of human-computer interaction. In this paper, we propose an SER network based on a Graph Isomorphism Network with Weighted Multiple Aggregators (WMA-GIN), which can effectively handle the problem of ...

Graph Isomorphism and Hybrid-Order Residual Gated Graph Neural Network for Session-Based Recommendation [PDF]

open access: yesJisuanji kexue yu tansuo
Session-based recommendation aims to predict which item will be clicked next for the current session. Aiming at the shortcomings of existing session recommendation models based on graph neural network, this paper proposes a model named graph isomorphism ...

Interaction graphs of isomorphic automata networks I: Complete digraph and minimum in-degree

open access: yesJournal of Computer and System Sciences, 2023
An automata network with $n$ components over a finite alphabet $Q$ of size $q$ is a discrete dynamical system described by the successive iterations of a function $f:Q^n\to Q^n$. In most applications, the main parameter is the interaction graph of $f$: the digraph with vertex set $[n]$ that contains an arc from $j$ to $i$ if $f_i$ depends on input $j$.

Symmetry in complex networks

open access: yes, 2008
We consider the size and structure of the automorphism groups of a variety of empirical ‘real-world’ networks and find that, in contrast to classical random graph models, many real-world networks are richly symmetric.

Analyzing single-valued neutrosophic fuzzy graphs through matroid perspectives

open access: yesAin Shams Engineering Journal
We hope to present this paper on the emergence of a novel category of matroids derived from single-valued neutrosophic (SVN) fuzzy-graphs. The findings of this study make a substantial contribution to both matroid theory and the field of neutrosophic ...

Investigating Hypernode Classification of Complex Systems Based on High-order Graph Neural Networks

open access: yesGuidance, Navigation and Control
Investigating latent interactions beyond direct connections is essential for analyzing complex networks. However, traditional graph structures often fail to capture complex relationships, especially in the high-order interactions among multiple ...
