DPAR: Decoupled Graph Neural Networks with Node-Level Differential Privacy

1 code implementation10 Oct 2022 Qiuchen Zhang, Hong kyu Lee, Jing Ma, Jian Lou, Carl Yang, Li Xiong

The key idea is to decouple the feature projection and message passing via a DP PageRank algorithm which learns the structure information and uses the top-$K$ neighbors determined by the PageRank for feature aggregation.
