Graph sparsification

WebJun 23, 2024 · Learnt Sparsification for Interpretable Graph Neural Networks. Graph neural networks (GNNs) have achieved great success on various tasks and fields that require relational modeling. GNNs aggregate node features using the graph structure as inductive biases resulting in flexible and powerful models. However, GNNs remain hard … WebOct 13, 2024 · To address these questions, we propose Sparsified Graph Convolutional Network (SGCN), a neural network graph sparsifier that sparsifies a graph by pruning some edges. We formulate sparsification as an optimization problem and solve it by an Alternating Direction Method of Multipliers (ADMM).
