MinCUT Pooling in Graph Neural Networks – Daniele Grattarola

Web3 Multi-channel Graph Convolutional Networks The pooling algorithm has its own bottlenecks in graph rep-resentation learning. The input graph is pooled and distorted gradually, which makes it hard to distinguish heterogeneous graphs at higher layers. The single pooled graph at each layer cannot preserve the inherent multi-view pooled struc … WebTo address this problem, DiffPool starts with the most primitive graph as the input graph for the first iteration, and each layer of GNN generates an embedding vector for all nodes in the graph. These embedding vectors are then input into the pooling module to produce a coarsened graph with fewer nodes, including the adjacency matrix and ...
