A Non-Asymptotic Analysis of Oversmoothing in Graph Neural Networks [PDF]

open access: yesInternational Conference on Learning Representations, 2022
Oversmoothing is a central challenge of building more powerful Graph Neural Networks (GNNs). While previous works have only demonstrated that oversmoothing is inevitable when the number of graph convolutions tends to infinity, in this paper, we precisely

On harmonious chromatic number of triple star graph [PDF]

open access: yesJournal of Hyperstructures, 2016
A Harmonious coloring of a graph G is a proper vertex coloring of G, in which every pair of colors appears on at most one pair of adjacent vertices and the harmonious chromatic number of graph G is the minimum number of colors needed for the harmonious ...

On the r-dynamic coloring of some fan graph families

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2021
In this paper, we determine the r-dynamic chromatic number of the fan graph Fm,n and determine sharp bounds of this graph invariant for four related families of graphs: The middle graph M(Fm,n), the total graph T (Fm,n), the central graph C(Fm,n) and the

Adaptive Propagation Graph Convolutional Networks Based on Attention Mechanism

open access: yesInformation, 2022
The main steps in a graph neural network are message propagation and aggregation between nodes. Message propagation allows messages from distant nodes in the graph to be transmitted to the central node, while feature aggregation allows the central node ...

Graph neural networks in particle physics [PDF]

open access: yesMachine Learning: Science and Technology, 2020
Particle physics is a branch of science aiming at discovering the fundamental laws of matter and forces. Graph neural networks are trainable functions which operate on graphs—sets of elements and their pairwise relations—and are a central method within ...
