Graph neural networks on heterophilous graphs: performance analysis and new architectures

Presenter: Andrea CavalloMonday, December 5th, 2022 17:00Location: SmartData@Covivio Graph Neural Networks (GNNs) achieve state-of-the-art performance on several tasks on graph-structured data. Their success is related to their capability to generate embeddings that model the entire neighborhood of a node, instead of just the node itself. This approach is very effective on homophilous graphs, i.e. graphs where same-type nodes tend to […]
