Structure-Adaptive Threshold Learning via sparse representation for Spiking Graph Neural Network

Experimental results validate the effectiveness of the structure-adaptive threshold mechanism for low-power spiking graph learning and design an alternating soft-fusion-hard-grouping training strategy that decouples structure-aware threshold generation from pattern-specific threshold optimization.

Sparse Structural Knowledge Enhanced Graph Neural Networks for Anomaly Detection in Social Networks

: Social network platforms have become primary channels for information dissemination, yet they are increasingly exploited by anomalous users such as bots, fake accounts, and coordinated disinformation spreaders. These malicious actors manipulate public opinion, spread misinformation and undermine platform integrity, p...
