LAARA: Layer-Aware Adaptive Rank Allocation for Parameter-Efficient Fine-Tuning
Article summary
Quick briefing — cleaned from the original RSS feed
arXiv:2607.19391v1 Announce Type: new Abstract: Low-Rank Adaptation is widely used for parameter-efficient fine-tuning, yet existing methods typically assign the same adapter rank to every transformer layer despite their heterogeneous adaptation requirements. In this work, we show theoretically and empirically that uniform rank allocation is fundamentally suboptimal. Motivated by this observation, we propose LAARA (Layer Aware Adaptive Rank Allocation framework), a search-free framework that…
