WebJun 22, 2024 · DiffPool learns a differentiable soft cluster assignment for nodes at each layer of a deep GNN, mapping nodes to a set of clusters, which then form the coarsened input for the next GNN layer. Our experimental results show that combining existing GNN methods with DiffPool yields an average improvement of 5-10 benchmarks, compared to … WebNov 26, 2024 · Nodes at the lth layer of the DIFFPOOL are the same as the clusters generated at the \(l-1\) th layer. Suppose the input graph is denoted by \(G=(V,E)\) with a set of N nodes V and a set of edges E and is described by an adjacency matrix \(A \in R^{N \times N}\) and node features matrix \(X \in R^{N \times F}\) where F is the feature …

WebApr 7, 2024 · To 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 ...
