Dhgnn: dynamic hypergraph neural networks
Webnetwork model. The existing hypergraph neural networks show better performance in node classification tasks and so on, while they are shallow network because of over-smoothing, over-fitting and gradient vanishment. To tackle these issues, we present a … Webdata and improves the results of SSL. Jiang et al. [28] proposed a dynamic hypergraph neural network framework (DHGNN) to solve the problem that the hypergraph structure cannot be updated automatically in hypergraph neural networks, thus limiting the lack of feature representation capability of changing data.

Web2.1 Hypergraph Neural Networks Graphs have limitations for representing high-order relation-ships. In a hypergraph, the complex relationships are encoded by hyperedges that can connect any number of nodes. [Zhou et al., 2006] introduced hypergraph to model high-order re-lations for semi-supervised classication and clustering of nodes. WebAs is illustrated in Figure 2, a DHGNN layer consists of two major part: dynamic hypergraph construction (DHG) and hypergraph convolution (HGC). We will first introduce these two parts in...
