Web5 apr. 2024 · Hypergraphs vs. Graphs. To better understand the concept of hypergraph networks, let’s compare them to traditional graphs. A graph is a collection of vertices (also known as nodes) connected by edges. The edges in a graph represent the relationships between vertices, which can be binary or non-binary. Web6 nov. 2024 · In particular, a 2-uniform hypergraph is simply a graph. All hypergraphs H can be expressed as the disjoint union of d-uniform hypergraphs H = ⋃ H d, where H d = (V, E d), E d ⊆ E are all hyperedges of size d, and is the d-degree of vertex v. As for graphs, the volume of a vertex subset A ⊆ V is vol H (A) = ∑ v∈A deg H (v). netherland schoolWebTo this end, we propose Hierarchical Hypergraph Matching Networks (H2sup>MN) to calculate the similarities between graph pairs with arbitrary structure.
