A hypergraph model for representing scientific output

WebIntroduction Hypergraph Contrastive Collaborative Filtering (HCCF) devises parameterized hypergraph neural network and hypergraph-graph contrastive learning, to relieve the over-smoothing issue for conventional graph neural networks, and address the sparse and skewed data distribution problem in collaborative filtering. Citation Web6. Hypergraph Neural Network (HNN) We further compare our model performances with two state-of-the-art hypergraph neural network models: HGNN [19] and HyperGAT [17]. HGNN presents a generalized hyperedge spectral convolution operation for hy-pergraph learning. HGNN generates the representation of nodes by aggregating hyperedges. pteridophytes scientific name

Web7 jan. 2024 · A directed hypergraph consists of a set of vertices V and a set of hyperarcs H, where a hyperarc is a pair < S, v >, S non empty subset of V and v ∈ V. S is also called the tail of the hyperarc, while v is the head. Several notions, such as paths and cycles can be naturally extended from digraphs to directed hypergraphs. pteridophytes images
