SketchGuard: Scaling Byzantine-Robust Decentralized Federated Learning via Sketch-Based Screening

This paper proposes SketchGuard, a novel framework that scales Byzantine-robust decentralized federated learning through sketch-based compression, achieving up to 82% reduction in computation time and 50-70% communication savings while maintaining identical robustness to state-of-the-art methods.
