Misclassification Rate and Privacy-Utility Trade-offs in Graph Convolutional Networks via Subsampling Stability

Yexin Zhang, Zhongtian Ma, Qiaosheng Zhang +1

We study differential privacy (DP) in Graph Convolutional Networks (GCNs) through the framework of \textit{subsampling stability}. We derive upper bounds on the misclassification r…

Gated Graph Attention Networks with Learnable Temperature

Zhongtian Ma, Hao Wu, Yexin Zhang +2

Graph attention networks learn neighbor importance through data-dependent coefficients, but standard layers lack explicit control over unreliable feature dimensions and use fixed s…
