WebMay 10, 2024 · Although graph contrastive learning has shown outstanding performance in self-supervised graph learning, using it for graph clustering is not well explored. We propose Gaussian mixture information maximization (GMIM) which utilizes a mutual information maximization approach for node embedding. WebIn this work, we study node classification in a hierarchical graph perspective which arises in many domains such as social network and document collection. In the hierarchical graph, each node is represented with one graph instance. We propose the Hierarchical Graph Mutual Information (HGMI) to model consistency among different levels of hierarchical …
WebGraph neural network (GNN) is a powerful representation learning framework for graph-structured data. Some GNN-based graph embedding methods, including variational graph autoencoder (VGAE), have been presented recently. WebNode-to-Neighbourhood (N2N) mutual information max-imization essentially encourages graph smoothing based on a quantifiable graph smoothness metric. Following In-foNCE [22], the mutual information can be optimized by a surrogate contrastive loss, where the key boils down to positive sample definition and selection.
