SEA: Graph Shell Attention in Graph Neural Networks

open access: yes, 2023
A common issue in Graph Neural Networks (GNNs) is known as over-smoothing. By increasing the number of iterations within the message-passing of GNNs, the nodes' representations of the input graph align with each other and become indiscernible. Recently, it has been shown that increasing a model's complexity by integrating an attention mechanism yields ...

Relational Graph Attention Networks

open access: yesCoRR, 2019
We investigate Relational Graph Attention Networks, a class of models that extends non-relational graph attention mechanisms to incorporate relational information, opening up these methods to a wider variety of problems. A thorough evaluation of these models is performed, and comparisons are made against established benchmarks.

Predicting Propositional Satisfiability Based on Graph Attention Networks

open access: yesInternational Journal of Computational Intelligence Systems, 2022
Boolean satisfiability problems (SAT) have very rich generic and domain-specific structures. How to capture these structural features in the embedding space and feed them to deep learning models is an important factor influencing the use of neural ...
