WebOct 31, 2024 · Graph Neural Networks. As seen above, shallow embedding methods have certain limitations that impact their ability to perform in real-life scenarios. To remediate these issues we take a look at GNNs. There are broadly two types of neural network-based node embedding approaches : 1. Message Passing-Based GCNs. WebPrincipal Neighbourhood Aggregation Layer. We added a new GNN module PNAConv introduced in Principal Neighbourhood Aggregation for Graph Nets. ... (PNA) improves the expressive power of a GNN by combining multiple aggregation functions with degree-scalars, thus making it a state-of-the-art baseline for many graph classification tasks.
