Dual-level Hypergraph Contrastive Learning with Adaptive Temperature Enhancement

Published in WWW, 2024

We propose a novel dual-level HyperGraph Contrastive Learning framework with Adaptive Temperature (HyGCL-AdT) to boost contrastive learning over hypergraphs. Our source code is available here.

Hypergraph Contrastive Learning for Drug Trafficking Community Detection

Published in ICDM, 2023

In this work, we propose a novel HyperGraph Contrastive Learning framework called HyGCL-DC that employs hypergraph to model the higher-order relationships among users to detect Drug trafficking Communities. Our newly collected dataset and source code is available here.

Adaptive Expansion for Hypergraph Learning

Published in Under Review, 2023

In this work, we propose a novel CE-based Adaptive Expansion method called AdE to expand hypergraphs into weighted graphs that preserve the higher-order hypergraph structure information.
