Measuring and Relieving the Over-smoothing Problem for Graph Neural Networks from the Topological View [PDF]

open access: yesAAAI Conference on Artificial Intelligence, 2019
Graph Neural Networks (GNNs) have achieved promising performance on a wide range of graph-based tasks. Despite their success, one severe limitation of GNNs is the over-smoothing issue (indistinguishable representations of nodes in different classes).

Factor Graph Neural Networks

open access: yes, 2023
In recent years, we have witnessed a surge of Graph Neural Networks (GNNs), most of which can learn powerful representations in an end-to-end fashion with great success in many real-world applications. They have resemblance to Probabilistic Graphical Models (PGMs), but break free from some limitations of PGMs.
