Dual-branch Density Ratio Estimation for Signed Network Embedding

2022 · Proceedings of the ACM Web Conference 2022

Signed network embedding (SNE) has received considerable attention in recent years. A mainstream idea of SNE is to learn node representations by estimating the ratio of sampling densities. Though achieving promising performance, these methods based …

Exploring Sparsity in Graph Transformers

2023 · arXiv (Cornell University)

Graph Transformers (GTs) have achieved impressive results on various graph-related tasks. However, the huge computational cost of GTs hinders their deployment and application, especially in resource-constrained environments. Therefore, in this paper, we explore the feasibility …
