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.

Hypergraph+: An Improved Hypergraph-Based Task-Scheduling Algorithm for Massive Spatial Data Processing on Master-Slave Platforms

open access: yesISPRS International Journal of Geo-Information, 2016
Spatial data processing often requires massive datasets, and the task/data scheduling efficiency of these applications has an impact on the overall processing performance.

Enhancing Hypergraph Neural Networks with Intent Disentanglement for Session-based Recommendation

open access: yesAnnual International ACM SIGIR Conference on Research and Development in Information Retrieval, 2022
Session-based recommendation (SBR) aims at the next-item prediction with a short behavior session. Existing solutions fail to address two main challenges: 1) user interests are shown as dynamically coupled intents, and 2) sessions always contain noisy ...

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

Session-based Recommendation with Hypergraph Attention Networks [PDF]

open access: yesSDM, 2021
Session-based recommender systems aim to improve recommendations in short-term sessions that can be found across many platforms. A critical challenge is to accurately model user intent with only limited evidence in these short sessions. For example, is a

Hypergraph Contextuality [PDF]

open access: yesEntropy, 2019
Quantum contextuality is a source of quantum computational power and a theoretical delimiter between classical and quantum structures. It has been substantiated by numerous experiments and prompted generation of state independent contextual sets, that is, sets of quantum observables capable of revealing quantum contextuality for any quantum state of a ...

Smallworldness in hypergraphs

open access: yesJournal of Physics: Complexity, 2023
Abstract Most real-world networks are endowed with the small-world property, by means of which the maximal distance between any two of their nodes scales logarithmically rather than linearly with their size. The evidence sparkled a wealth of studies trying to reveal possible mechanisms through which the pairwise interactions amongst the ...

Controllability of Hypergraphs [PDF]

open access: yesIEEE Transactions on Network Science and Engineering, 2021
In this paper, we develop a notion of controllability for hypergraphs via tensor algebra and polynomial control theory. Inspired by uniform hypergraphs, we propose a new tensor-based multilinear dynamical system representation, and derive a Kalman-rank-like condition to determine the minimum number of control nodes (MCN) needed to achieve ...

Metro Passenger Flow Prediction via Dynamic Hypergraph Convolution Networks

open access: yesIEEE transactions on intelligent transportation systems (Print), 2021
Metro passenger flow prediction is a strategically necessary demand in an intelligent transportation system to alleviate traffic pressure, coordinate operation schedules, and plan future constructions. Graph-based neural networks have been widely used in

Blocks of Hypergraphs [PDF]

open access: yes, 2011
A support of a hypergraph H is a graph with the same vertex set as H in which each hyperedge induces a connected subgraph. We show how to test in polynomial time whether a given hypergraph has a cactus support, i.e. a support that is a tree of edges and cycles.
