Weberal classic GNNs, like GCN, GAT, GIN and GraphSAGE di-rectly into hypergraphs, termed UniGCN, UniGAT, UniGIN and UniSAGE, respectively. UniGNNs consistently outper-form the state-of-art approaches in hypergraph learning tasks. A 2. We propose the UniGCNII, the ﬁrst deep hypergraph neural network and verify its effectiveness in resolving the Webhypergraph definitions. The rationale behind exploiting and integrating hypergraphs by extending GCN is that hypergraphs provide a more flexible network representation that can contain additional and richer information compared to individual, single graph GCNs on local network topol-ogy. It has been found that the optimal number of GCN layers is
