Title: ADAPT-FED: Adaptive Federated Optimization with Learning Stability
Primary area: optimization
Keywords: Federated Learning, Optimization

Abstract: Federated Learning (FL) frequently exhibits poor generalization due to unstable training across heterogeneous clients. Although training instability can accelerate learning, it often compromises generalization, resulting in a fundamental tension within FL. This work introduces \sysname, a framework that adaptively regulates training dynamics to leverage the advantages of instability while mitigating its adverse effects. As a result, \sysname enables more stable and consistent learning in privacy-constrained environments. Experimental results on standard benchmarks demonstrate that \sysname enhances generalization and convergence relative to state-of-the-art FL optimization algorithms.
