Unifying Invariant and Variant Knowledge With Dual‐Hypergraph Contrastive Evolution for Temporal Knowledge Graph Reasoning

open access: yesInternational Journal of Intelligent Systems, Volume 2026, Issue 1, 2026.
Temporal knowledge graph reasoning (TKGR) excels at inferring missing event‐centric facts within a timeline, thereby mitigating the inherent incompleteness of real‐world data. Existing TKGR methods predominantly exploit intrasnapshot structural patterns and intersnapshot temporal dependencies.

Temporal Knowledge Graph Reasoning With Historical Data Correlation in Agriculture

open access: yesInternational Journal of Intelligent Systems, Volume 2026, Issue 1, 2026.
In terms of temporal dependencies of agricultural data, temporal knowledge graph reasoning is widely used to provide dynamic decision‐making for crop monitoring and disease prediction. Since periodicity, repeatability, and persistence always exist in large, various agricultural data, it is difficult to effectively capture the above important features ...

Self-Supervised Hypergraph Representation Learning for Sociological Analysis

open access: yes, 2023
Modern sociology has profoundly uncovered many convincing social criteria for behavioral analysis. Unfortunately, many of them are too subjective to be measured and very challenging to be presented in online social networks (OSNs) for the large data ...

Beyond Hypergraph Dualization

open access: yes, 2016
International audienceThis problem concerns hypergraph dualization and generalization to poset dualization. A hypergraph H = (V, E) consists of a finite collection E of sets over a finite set V , i.e. E ⊆ P(V) (the powerset of V).

Group Identification via Transitional Hypergraph Convolution with Cross-view Self-supervised Learning

open access: yes, 2023
With the proliferation of social media, a growing number of users search for and join group activities in their daily life. This develops a need for the study on the group identification (GI) task, i.e., recommending groups to users.

Unified Low-Rank Subspace Clustering with Dynamic Hypergraph for Hyperspectral Image

open access: yes, 2021
Low-rank representation with hypergraph regularization has achieved great success in hyperspectral imagery, which can explore global structure, and further incorporate local information.

Self-complementing permutations of k-uniform hypergraphs [PDF]

open access: yes, 2009
Graphs and AlgorithmsInternational audienceA k-uniform hypergraph H = ( V; E) is said to be self-complementary whenever it is isomorphic with its complement (H) over bar = ( V; ((V)(k)) - E).
