DAETG: Dual-Stage Attention Embedding for Community Detection on Textual-Edge Graphs

Textual-edge graphs represent interactions through both connectivity and relation-specific text. Learning community structure from these graphs requires an encoder that preserves the relevance of individual relations when combining semantic and structural information. We propose Dual-Stage Attention Embedding for Commu...

Decentralized Topology Robustness Optimization for IoT via Multi-Agent Graph Reinforcement Learning

The robustness of Internet of Things (IoT) communication topologies against internal failures and external perturbations is a fundamental prerequisite for maintaining system stability. This paper studies IoT topology robustness from two perspectives: robustness metric and optimization. Existing robustness metrics, prim...
