Hypergraph gnn
Webto unify hypergraph and GNN models using hypergraph star expansion. Many variations of GNNs can be incorporated in UniGNN. [Chien et al., 2024] proposes a general HGNN framework that implements HGNN layers as compositions of two multiset functions and covers propagation methods of most existing HGNNs. 2.2 Graph Structure Learning WebA few hypergraph-based methods have recently been proposed to address the problem of multi-modal/multi-type data correlation by directly concatenating the hypergraphs …
