A Survey on Hypergraph Mining: Patterns, Tools, and Generators [PDF]

open access: yesACM Computing Surveys
Hypergraphs, which belong to the family of higher-order networks, are a natural and powerful choice for modeling group interactions in the real world.

Prediction of Graduation Development Based on Hypergraph Contrastive Learning With Imbalanced Sampling

open access: yesIEEE Access, 2023
With the increasingly competitive job market, the employment issue for college graduates has received more and more attention. Predicting graduation development can help students understand their suitable graduation development, thus easing the pressure ...

Hypergraph polytopes

open access: yesTopology and its Applications, 2011
We investigate a family of polytopes introduced by E.M.\ Feichtner, A.\ Postnikov and B.\ Sturmfels, which were named nestohedra. The vertices of these polytopes may intuitively be understood as constructions of hypergraphs. Limit cases in this family of polytopes are, on the one end, simplices, and, on the other end, permutohedra.

Quasi‐random hypergraphs [PDF]

open access: yesRandom Structures & Algorithms, 1989
AbstractWe introduce an equivalence class of varied properties for hypergraphs. Any hypergraph possessing any one of these properties must of necessity possess them all. Since almost all random hypergraphs share these properties, we term these properties quasi‐random.

High-Quality Hypergraph Partitioning [PDF]

open access: yesACM Journal of Experimental Algorithmics, 2021
Hypergraphs are a generalization of graphs where edges (aka nets) are allowed to connect more than two vertices. They have a similarly wide range of applications as graphs.

Almost Self-Complementary Uniform Hypergraphs

open access: yesDiscussiones Mathematicae Graph Theory, 2018
A k-uniform hypergraph (k-hypergraph) is almost self-complementary if it is isomorphic with its complement in the complete k-uniform hypergraph minus one edge. We prove that an almost self-complementary k-hypergraph of order n exists if and only if (nk)$\

Algebraic structures and lattice properties of hypergraph Pre-Rough sets‎ [PDF]

open access: yesMathematics and Computational Sciences
The study introduces and examines the concept of hypergraph pre-rough sets, which are developed by combining minimum soft descriptions with hypergraph structures.

Generative hypergraph clustering: From blockmodels to modularity [PDF]

open access: yesScience Advances, 2021
Novel clustering techniques enable the detection of modules in large datasets with multiway interactions. Hypergraphs are a natural modeling paradigm for networked systems with multiway interactions.

Individual Differences in Dynamic Functional Brain Connectivity across the Human Lifespan. [PDF]

open access: yesPLoS Computational Biology, 2016
Individual differences in brain functional networks may be related to complex personal identifiers, including health, age, and ability. Dynamic network theory has been used to identify properties of dynamic brain function from fMRI data, but the majority

Optimal Query Complexity for Reconstructing Hypergraphs [PDF]

open access: yes, 2010
In this paper we consider the problem of reconstructing a hidden weighted hypergraph of constant rank using additive queries. We prove the following: Let $G$ be a weighted hidden hypergraph of constant rank with n vertices and $m$ hyperedges. For any $m$
