Federated Unlearning via Class-Discriminative Pruning

no code implementations22 Oct 2021 Junxiao Wang, Song Guo, Xin Xie, Heng Qi

Evaluated on CIFAR10 dataset, our method accelerates the speed of unlearning by 8. 9x for the ResNet model, and 7. 9x for the VGG model under no degradation in accuracy, compared to retraining from scratch.

Breaking the Expressive Bottlenecks of Graph Neural Networks

1 code implementation14 Dec 2020 Mingqi Yang, Yanming Shen, Heng Qi, BaoCai Yin

Recently, the Weisfeiler-Lehman (WL) graph isomorphism test was used to measure the expressiveness of graph neural networks (GNNs), showing that the neighborhood aggregation GNNs were at most as powerful as 1-WL test in distinguishing graph structures.
