arXiv:2606.10196v1 Announce Type: cross Abstract: Parameter-efficient fine-tuning (PEFT) aims to adapt pretrained models with a small trainable parameter subset, however, most existing methods choose this subset from fixed architectural heuristics rather than using dynamic, task-aware criteria. We introduce \textbf{FisherAdapTune}, a Fisher-guided Adaptive Fine-Tuning framework that progressively selects parameter groups by tracking the temporal drift of their Fisher geometry. Starting from a PAC-Bayesian view of fine-tuning, we decompose the generalization error bound into Fisher-weighted upd
The proliferation of increasingly large pretrained models necessitates more efficient fine-tuning methods, driving current research towards adaptive parameter selection.
Adaptive fine-tuning methods like FisherAdapTune could significantly reduce the computational cost and time associated with deploying and updating large AI models, accelerating their practical application.
Current fine-tuning practices that rely on fixed heuristics for parameter selection may be superseded by dynamic, task-aware approaches, making model adaptation more efficient and effective.
