Global Adaptive Momentum Meets Local Personalized Perturbation: Efficient Federated LLM Fine-Tuning with Zeroth-Order Gradients (2026.acl-long)

Copied to clipboard

Challenge: federated fine-tuning of large language models provides privacy-preserving approach to deploying pervasive generative AI services.
Approach: They propose a federated framework for fine-tuning large language models . they propose unified optimization and local personalized perturbation for ZO gradients .
Outcome: The proposed framework outperforms existing methods for integrating ZO gradients in federated learning over diverse heterogeneous data settings.
