DECA: Decentralizing Block-Wise Adam for Efficient LLM Full-Parameter Fine-Tuning on Non-IID Data
arXiv:2606.03209v1 Announce Type: new Abstract: Fine-tuning large language models (LLMs) in privacy-sensitive and resource-constrained environments remains challenging. Since training data are often distributed across multiple clients, decentralized fine-tuning offers a natural paradigm for collaborative adaptation without a central server. However, enabling full-parameter fine-tuning (FPFT) in this decentralized setting is difficult: FPFT provides strong adaptation capacity but incurs prohibitive resource consumption for billion-scale models. Existing decentralized LLM fine-tuning methods the
The increasing scale of LLMs and growing privacy concerns are pushing the need for decentralized and efficient fine-tuning methods, especially as federated learning gains traction.
This development addresses key challenges in large language model deployment, enabling wider adoption in privacy-sensitive sectors and distributed environments, away from centralized cloud providers.
The ability to fine-tune full-parameter LLMs decentralization, particularly on non-IID data, reduces the compute and data-centralization dependencies for advanced AI adaptation.
