Multi-Level Refinement Algorithm of Weighted Hypergraph Partitioning Problem

open access: yesJournal of Intelligent Systems, 2017
The formal description of weighted hypergraph partitioning problem is presented. We describe the solution of the weighted hypergraph partitioning problem based on the multi-level method.

The mixed hypergraphs [PDF]

open access: yesComputer Science Journal of Moldova, 1993
We introduce the notion of an anti-edge of a hypergraph, which is a non-overall polychromatic subset of vertices. The maximal number of colors, for which there exists a coloring of a hypergraph using all colors, is called an upper chromatic number of a ...

On $\alpha$-spectral theory of a directed k-uniform hypergraph [PDF]

open access: yesComputer Science Journal of Moldova, 2020
In this paper, we study a k-uniform directed hypergraph in general form and introduce its adjacency tensor, Laplacian tensor and signless Laplacian tensor. For the $k$-uniform directed hypergraph $\mathcal{H}$ and $0\leq \alpha

Semi-Supervised Classification via Hypergraph Convolutional Extreme Learning Machine

open access: yesApplied Sciences, 2021
Extreme Learning Machine (ELM) is characterized by simplicity, generalization ability, and computational efficiency. However, previous ELMs fail to consider the inherent high-order relationship among data points, resulting in being powerless on ...

Hypergraph Modelling for Geometric Model Fitting

open access: yes, 2016
In this paper, we propose a novel hypergraph based method (called HF) to fit and segment multi-structural data. The proposed HF formulates the geometric model fitting problem as a hypergraph partition problem based on a novel hypergraph model.

Extreme violation of local realism in quantum hypergraph states

open access: yes, 2016
Hypergraph states form a family of multiparticle quantum states that generalizes the well-known concept of Greenberger-Horne-Zeilinger states, cluster states, and more broadly graph states.

Ce‐LLMs: Status and trends of education‐specific large language models developed in China

open access: yesFuture in Educational Research, EarlyView.
Abstract The prevalence of AI hallucination in general‐purpose large language models (LLMs) poses significant pedagogical challenges, particularly in terms of content credibility and reliability. In response, China has launched the development of education‐specific LLMs as a national strategic initiative. However, current reports on Chinese educational

Completion and decomposition of hypergraphs by domination hypergraphs

open access: yes, 2023
A graph consists of a finite non-empty set of vertices and a set of unordered pairs of vertices, called edges. A dominating set of a graph is a set of vertices D such that every vertex not in D is adjacent to some vertex in D. A hypergraph on a finite set X is a collection of subsets of X, none of which is a proper subset of another.

Random walks on hypergraphs [PDF]

open access: yesPhysical Review E, 2020
In the last twenty years network science has proven its strength in modelling many real-world interacting systems as generic agents, the nodes, connected by pairwise edges. Yet, in many relevant cases, interactions are not pairwise but involve larger sets of nodes, at a time.
