FedSteer: Taming Extreme Gradient Staleness in Federated Learning with Corrective Projections and Caching
arXiv:2606.10124v1 Announce Type: new Abstract: Federated learning (FL) is often subject to aggregation variance if clients do not consistently participate in training rounds. While reusing stale model updates from inactive clients is a common technique to reduce this variance, we find that with skewed client participation, the resulting update staleness can become severe enough to destabilize training. To remedy this, we propose FedSteer, a novel method that constructs a gradient subspace from a cache of recent client gradients to serve as a low-dimensional representation of the current optim
The increasing complexity and scale of federated learning deployments are exposing fundamental challenges like gradient staleness, amplified by inconsistent client participation.
Improving the stability and efficiency of federated learning is crucial for its broader adoption in privacy-preserving AI applications, especially in distributed AI systems.
This research introduces a novel method to mitigate the destabilizing effects of extreme gradient staleness in federated learning, potentially enabling more robust and scalable FL implementations.
