Pytorch hypergraph
WebA hypergraph is usually characterized by its incidence matrix H, whose rows represent nodes and columns represent hyperedges. An entry Hij is 1 if hyperedge j includes node i, or 0 otherwise. For example, the hypergraph in the figure above can be characterized by a 11 × 5 matrix as follows: WebDHG is built upon Pytorch, and any Pytorch-based models can be integrated into DHG. If you are familiar with Pytorch, you can easily use DHG. Powerful API for Designing GNNs and HGNNs DHG provides various Laplacian matrices and message passing functions to help build your spectral/spatial-based models, respectively.

WebSep 7, 2024 · 1 As you can see in the docs: Since this feature is still experimental, some operations, e.g., graph pooling methods, may still require you to input the edge_index format. You can convert adj_t back to (edge_index, edge_attr) via: row, col, edge_attr = adj_t.t ().coo () edge_index = torch.stack ( [row, col], dim=0) Share Improve this answer Follow WebSep 7, 2024 · A popular learning paradigm is hypergraph-based semi-supervised learning (SSL) where the goal is to assign labels to initially unlabeled vertices in a hypergraph. Motivated by the fact that a graph convolutional network (GCN) has been effective for graph-based SSL, we propose HyperGCN, a novel GCN for SSL on attributed hypergraphs.
