Contrastive Sequential Interaction Network Learning on Co-Evolving Riemannian Spaces

no code implementations2 Jan 2024 Li Sun, Junda Ye, Jiawei Zhang, Yong Yang, Mingsheng Liu, Feiyang Wang, Philip S. Yu

To address the aforementioned issues, we propose a novel Contrastive model for Sequential Interaction Network learning on Co-Evolving RiEmannian spaces, CSINCERE.

Motif-aware Riemannian Graph Neural Network with Generative-Contrastive Learning

1 code implementation2 Jan 2024 Li Sun, Zhenhao Huang, Zixi Wang, Feiyang Wang, Hao Peng, Philip Yu

In light of the issues above, we propose the problem of \emph{Motif-aware Riemannian Graph Representation Learning}, seeking a numerically stable encoder to capture motif regularity in a diverse-curvature manifold without labels.

Contrastive Graph Clustering in Curvature Spaces

no code implementations5 May 2023 Li Sun, Feiyang Wang, Junda Ye, Hao Peng, Philip S. Yu

On the other hand, contrastive learning boosts the deep graph clustering but usually struggles in either graph augmentation or hard sample mining.

Self-Supervised Continual Graph Learning in Adaptive Riemannian Spaces

no code implementations30 Nov 2022 Li Sun, Junda Ye, Hao Peng, Feiyang Wang, Philip S. Yu

On the one hand, existing methods work with the zero-curvature Euclidean space, and largely ignore the fact that curvature varies over the coming graph sequence.

Hyperbolic Variational Graph Neural Network for Modeling Dynamic Graphs

no code implementations6 Apr 2021 Li Sun, Zhongbao Zhang, Jiawei Zhang, Feiyang Wang, Hao Peng, Sen Su, Philip S. Yu

To model the uncertainty, we devise a hyperbolic graph variational autoencoder built upon the proposed TGNN to generate stochastic node representations of hyperbolic normal distributions.
