Quantum chemical methods of force field parameterization such as the Seminario method encountercompute limitations at large scales. We present a GNN framework that outperforms the Seminario method by 34% in reproducing infrared bond frequencies across prevalent functional groups, and is up to seven orders of magnitude faster on larger molecules ...

A Performance Comparison of Graph Neural Networks and Standard Machine Learning Methods for Illegal Bitcoin Transaction Detection Based on the Elliptic Dataset [PDF]
Bitcoin allows users to complete transactions anonymously and operates without centralized management. Such inherent characteristics provide conditions for various illegal activities.

Graph Homomorphism Revisited for Graph Matching [PDF]
In a variety of emerging applications one needs to decide whether a graph G matches another Gp, i.e., whether G has a topological structure similar to that of Gp. The traditional notions of graph homomorphism and isomorphism often fall short of capturing

Relaxations of Graph Isomorphism [PDF]
We introduce a nonlocal game that captures and extends the notion of graph isomorphism. This game can be won in the classical case if and only if the two input graphs are isomorphic.

Polynomial-time algorithms for Subgraph Isomorphism in small graph classes of perfect graphs [PDF]
Given two graphs, Subgraph Isomorphism is the problem of deciding whether the first graph (the base graph) contains a subgraph isomorphic to the second graph (the pattern graph).

Graph hybrid neural network integration for enhanced diabetic retinopathy detection in retinal image
Diabetic retinopathy (DR) is a progressive microvascular complication of diabetes that affects the retina. This study presents a hybrid graph neural network (GNN) architecture that combines a graph isomorphism network (GIN) with GraphSAGE to improve ...
