arXiv:2605.21217v1 Announce Type: cross Abstract: Low-rank adaptation (LoRA) has emerged as a powerful tool for parameter-efficient fine-tuning of large language models (LLMs). This paper studies LoRA under a federated learning setting, enabling collaborative fine-tuning across clients while preserving parameter efficiency. We focus on a highly heterogeneous regime in which clients share only partial structure and a substantial subset may be contaminated. We propose Collaborative Low-rank Alignment and Identifiable Recovery (CLAIR), a contamination-aware framework that relies only on prelimina
The proliferation of powerful LLMs and the increasing focus on data privacy and distributed computation drive the need for efficient and secure fine-tuning methods like Federated LoRA.
This development addresses critical challenges in scaling LLM deployment, particularly for applications requiring data locality or sensitive information, opening new avenues for collaborative AI development.
The ability to fine-tune LLMs collaboratively and efficiently without pooling raw data significantly lowers barriers for enterprises and organizations to deploy specialized AI.
