Trust-Aware Topology Learning for Dynamic Decentralized Federated Learning under Adversaries

Shubham Vaishnav, Murtaza Rangwala, Ali Beikmohammadi +3

In dynamic mobile decentralized federated learning (DFL), adversaries can poison both model updates and the topology information devices use to choose collaborators. We present DMT…
