Kick Bad Guys Out! Zero-Knowledge-Proof-Based Anomaly Detection in Federated Learning

no code implementations6 Oct 2023 Shanshan Han, Wenxuan Wu, Baturalp Buyukates, Weizhao Jin, Qifan Zhang, Yuhang Yao, Salman Avestimehr, Chaoyang He

Federated Learning (FL) systems are vulnerable to adversarial attacks, where malicious clients submit poisoned models to prevent the global model from converging or plant backdoors to induce the global model to misclassify some samples.

FedRule: Federated Rule Recommendation System with Graph Neural Networks

2 code implementations13 Nov 2022 Yuhang Yao, Mohammad Mahdi Kamani, Zhongwei Cheng, Lin Chen, Carlee Joe-Wong, Tianqiang Liu

Much of the value that IoT (Internet-of-Things) devices bring to ``smart'' homes lies in their ability to automatically trigger other devices' actions: for example, a smart camera triggering a smart lock to unlock a door.

Faithful Explanations for Deep Graph Models

no code implementations24 May 2022 Zifan Wang, Yuhang Yao, Chaoran Zhang, Han Zhang, Youjie Kang, Carlee Joe-Wong, Matt Fredrikson, Anupam Datta

Second, our analytical and empirical results demonstrate that feature attribution methods cannot capture the nonlinear effect of edge features, while existing subgraph explanation methods are not faithful.

FedGCN: Convergence-Communication Tradeoffs in Federated Training of Graph Convolutional Networks

1 code implementation NeurIPS 2023 Yuhang Yao, Weizhao Jin, Srivatsan Ravi, Carlee Joe-Wong

Methods for training models on graphs distributed across multiple clients have recently grown in popularity, due to the size of these graphs as well as regulations on keeping data where it is generated.

GCN-SE: Attention as Explainability for Node Classification in Dynamic Graphs

no code implementations11 Oct 2021 Yucai Fan, Yuhang Yao, Carlee Joe-Wong

These works, however, do not fully address the challenge of flexibly assigning different importance to snapshots of the graph at different times, which depending on the graph dynamics may have more or less predictive power on the labels.

Interpretable Clustering on Dynamic Graphs with Recurrent Graph Neural Networks

2 code implementations16 Dec 2020 Yuhang Yao, Carlee Joe-Wong

We characterize the optimal decay rate for each cluster and propose a clustering method that achieves almost exact recovery of the true clusters.
