Web29 mei 2024 · The mathematical object that natively represents multi-way interactions amongst entities is called a “hypergraph”. In contrast to a graph, in a hypergraph the relationships amongst entities (still called vertices) are connected generally by “hyperedges”, where each hyperedge is an arbitrary subset of vertices.

WebIn mathematics, a hypergraph is a generalization of a graph in which an edge can join any number of vertices.In contrast, in an ordinary graph, an edge connects exactly two vertices. Formally, a directed hypergraph [math]\displaystyle{ H }[/math] is a pair [math]\displaystyle{ H = (X,E) }[/math] where [math]\displaystyle{ X }[/math] is a set of … WebFor describing the influence of higher-order interactions in the rumor propagation, hypergraph theory is introduced in this paper. • The spreading rate in Hyper-SIR model based on higher-order group interactions is related to the size of groups, and the rumor propagation is not just spread by the point-to-point form. WebSpecifically, we present a hypergraph parser to imitate guiding perception to learn intra-modal object-wise relationships. It parses the input modality into irregular hypergraphs to mine semantic clues and generate robust mono-modal representations. kansas city chiefs directv

The issue is that hypergraph terminology is far less standardized than graph terminology, so the two links do not use the same definition. In particular, graphs usually allow only one edge, and if you have multiple edges it is then a multigraph. Note that you have to change the underlying mathematical structure to handle multiple ...
