DDGAD: Disagreement-Driven Graph Anomaly Detection via Adapt-Then-Combine
Yuxin Yang, Limei Hu, Feng Chen
Graph anomaly detection (GAD) commonly relies on message passing to jointly encode node attributes and neighborhood context. However, once the two are mixed, an abnormal post-encod…
Low-Communication Resilient Distributed Estimation Algorithm Based on Memory Mechanism
Wei Li, Limei Hu, Feng Chen +1
In multi-task adversarial networks, the accurate estimation of unknown parameters in a distributed algorithm is hindered by attacked nodes or links. To tackle this challenge, this…
Hybrid Near-Far Field 6D Movable Antenna Design Exploiting Directional Sparsity and Deep Learning
Xiaodan Shao, Limei Hu, Yulong Sun +7
Six-dimensional movable antenna (6DMA) has been identified as a new disruptive technology for future wireless systems to support a large number of users with only a few antennas. H…
Analysis of Age of Information in Dual Updating Systems
Zhengchuan Chen, Dapeng Deng, Howard H. Yang +5
We study the average Age of Information (AoI) and peak AoI (PAoI) of a dual-queue status update system that monitors a common stochastic process. Although the double queue parallel…
