Less Can Be More: Unsupervised Graph Pruning for Large-scale Dynamic Graphs

1 code implementation18 May 2023 Jintang Li, Sheng Tian, Ruofan Wu, Liang Zhu, Welong Zhao, Changhua Meng, Liang Chen, Zibin Zheng, Hongzhi Yin

We approach the problem by our proposed STEP, a self-supervised temporal pruning framework that learns to remove potentially redundant edges from input dynamic graphs.

Joint 3-D Positioning and Power Allocation for UAV Relay Aided by Geographic Information

no code implementations12 Oct 2021 Pengfei Yi, Liang Zhu, Lipeng Zhu, Zhenyu Xiao, Zhu Han, Xiang-Gen Xia

To improve communication capacity, we first model the blockage effect caused by buildings according to the three-dimensional (3-D) geographic information.

Memory Augmented Design of Graph Neural Networks

no code implementations1 Jan 2021 Tao Xiong, Liang Zhu, Ruofan Wu, Yuan Qi

Specifically, we allow every node in the original graph to interact with a group of memory nodes.
