Equivariant Hypergraph Diffusion Neural Operators

1 code implementation14 Jul 2022 Peihao Wang, Shenghao Yang, Yunyu Liu, Zhangyang Wang, Pan Li

Hypergraph neural networks (HNNs) using neural networks to encode hypergraphs provide a promising way to model higher-order relations in data and further solve relevant prediction tasks built upon such higher-order relations.

Neural Predicting Higher-order Patterns in Temporal Networks

2 code implementations10 Jun 2021 Yunyu Liu, Jianzhu Ma, Pan Li

HIT extracts the structural representation of a node triplet of interest on the temporal hypergraph and uses it to tell what type of, when, and why the interaction expansion could happen in this triplet.

Aspect-based Sentiment Classification via Reinforcement Learning
