Web17 uur geleden · An example notebook contains the basic pipeline of the work: Graph and Hypergraph-based representations of Free Associations; Features' Aggregation Strategies based on the above representations; Predicting a Target Feature (e.g., ground-truth concreteness) based on the other aggregated features; G123 Ego-Network. In 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 is a pair $${\displaystyle (X,E)}$$, where $${\displaystyle X}$$ is a set of … Meer weergeven Undirected hypergraphs are useful in modelling such things as satisfiability problems, databases, machine learning, and Steiner tree problems. They have been extensively used in machine learning tasks as the … Meer weergeven Although hypergraphs are more difficult to draw on paper than graphs, several researchers have studied methods for the visualization of hypergraphs. In one possible visual representation for hypergraphs, similar to the standard graph drawing style … Meer weergeven Because hypergraph links can have any cardinality, there are several notions of the concept of a subgraph, called subhypergraphs, partial hypergraphs and section hypergraphs. Let $${\displaystyle H=(X,E)}$$ be the hypergraph … Meer weergeven A parallel for the adjacency matrix of a hypergraph can be drawn from the adjacency matrix of a graph. In the case of a graph, the adjacency matrix is a square matrix which … Meer weergeven Many theorems and concepts involving graphs also hold for hypergraphs, in particular: • Matching in hypergraphs; • Vertex cover in hypergraphs (also known as: transversal); • Line graph of a hypergraph; Meer weergeven Classic hypergraph coloring is assigning one of the colors from set $${\displaystyle \{1,2,3,...,\lambda \}}$$ to every vertex of a hypergraph in such a way that each hyperedge … Meer weergeven Let $${\displaystyle V=\{v_{1},v_{2},~\ldots ,~v_{n}\}}$$ and $${\displaystyle E=\{e_{1},e_{2},~\ldots ~e_{m}\}}$$. Every hypergraph has an $${\displaystyle n\times m}$$ incidence matrix. For an undirected hypergraph, Meer weergeven
