Research on key node identification method based on multi-attribute fusion in complex networks

Accurate assessment of node importance in complex networks is crucial for enhancing network robustness and security, for instance, by protecting critical data nodes or reinforcing core hubs. However, existing importance metrics often struggle to simultaneously accommodate local connectivity, neighborhood influence an...

Objective Multi-Metric Fusion for Critical Node Identification via CRITIC and Global–Local Context Modeling

Accurately identifying critical nodes in complex networks and applying targeted protection strategies significantly enhances network security. Traditional importance metrics rely on a single topological feature and cannot fully capture node influence. Existing multi-attribute fusion methods integrate multiple structura...
