Happy to announce that our paper on "Principal Neighbourhood Aggregation for Graph Nets" was accepted at the GRL+ ICML 2020 Workshop! You can find the updated paper with new interesting results on arXiv!
New research on GNN expressivity! Generalising theoretical results from GIN to uncountable feature spaces, yielding PNA, an empirically powerful GNN aggregator.
