Hypergraph Motif Representation Learning

open access: yesProceedings of the 31st ACM SIGKDD Conference on Knowledge Discovery and Data Mining V.1
Hypergraphs have emerged as a powerful tool for representing high-order connections in real-world complex systems. Similar to graphs, local structural patterns in hypergraphs, known as high-order motifs (h-motifs), play a crucial role in network dynamics and serve as fundamental building blocks across various domains.

Adaptive Expansion for Hypergraph Learning

open access: yesCoRR
Hypergraph, with its powerful ability to capture higher-order relationships, has gained significant attention recently. Consequently, many hypergraph representation learning methods have emerged to model the complex relationships among hypergraphs. In general, these methods leverage classic expansion methods to convert hypergraphs into weighted or ...

Geometric Hypergraph Learning for Visual Tracking

open access: yesIEEE Transactions on Cybernetics, 2017
Graph based representation is widely used in visual tracking field by finding correct correspondences between target parts in consecutive frames. However, most graph based trackers consider pairwise geometric relations between local parts. They do not make full use of the target's intrinsic structure, thereby making the representation easily disturbed ...

Higher-Order Regularization Learning on Hypergraphs

open access: yesCoRR
Higher-Order Hypergraph Learning (HOHL) was recently introduced as a principled alternative to classical hypergraph regularization, enforcing higher-order smoothness via powers of multiscale Laplacians induced by the hypergraph structure. Prior work established the well- and ill-posedness of HOHL through an asymptotic consistency analysis in geometric ...
