FedSubMuon: Communication-Efficient Federated LLM Fine-Tuning via Structured Subspace Muon
Shaolong Chen, Youming Tao, Shuzhen Chen +3
Federated fine-tuning adapts large language models (LLMs) to decentralized client data, but its scalability in cross-device training is often limited by the high communication cost…

Second-Order Convergence in Private Stochastic Non-Convex Optimization
Youming Tao, Zuyuan Zhang, Dongxiao Yu +3
We investigate the problem of finding second-order stationary points (SOSP) in differentially private (DP) stochastic non-convex optimization. Existing methods suffer from two key…
