arXiv:2605.29317v2 Announce Type: replace Abstract: Parameter-efficient fine-tuning(PEFT) has largely focused on LoRA and its accuracy-oriented variants, leaving the original goal of reducing trainable parameters has receivedcomparatively little attention. We introduce FoRA, which revisits this goal by reducing the number of adapted layers rather than adapter rank. FoRA selects task-informative layers via a single-pass diagonal Fisher score (under 1% of training cost) and trains the LoRA down-projection at selected layers on the Stiefel manifold, preserving column orthonormality and effective
The continuous drive for more efficient AI models and the increasing computational demands of large models necessitate innovative PEFT techniques like FoRA to optimize resource utilization.
This development allows for more widespread and cost-effective fine-tuning of large language models, democratizing access to powerful AI capabilities and reducing operational overhead.
Fine-tuning AI models becomes significantly more parameter-efficient, potentially reducing computational costs and allowing deployment on resource-constrained hardware without major performance degradation.
