TaRA: Training-Aware Low-Rank Adaptation Initialization

TaRA: Training-Aware Low-Rank Adaptation Initialization proposes a new way to initialize LoRA by aligning the gradients of low‑rank factors with those of the full‑rank weight matrix. This approach directly incorporates training dynamics, improving gradient fidelity at the start of fine‑tuning while adding negligible computational cost. Experiments on a variety of challenging fine‑tuning tasks show that TaRA consistently outperforms existing state‑of‑the‑art initialization methods, offering a simple, robust, and scalable solution for effective LoRA initialization.

Sparsity-Aware Low-Rank Representation for Efficient Fine-Tuning of Large Language Models

arXiv:2601. 16991v3 Announce Type: replace-cross Abstract: Adapting large pre-trained language models to downstream tasks often entails fine-tuning millions of parameters or deploying costly dense weight updates, which hinders their use in resource-constrained environments.

One Shared LoRA Weight for MRI Reconstruction across Acceleration Factors

The paper introduces Shared LoRA, a parameter‑efficient approach for accelerated MRI reconstruction that uses a single set of LoRA adapters and a lightweight gating network to handle multiple acceleration factors. By freezing a pretrained SHFormer backbone and training the adapters on randomly sampled acceleration factors, the method learns reconstruction knowledge across factors. Experiments demonstrate that Shared LoRA achieves competitive PSNR and SSIM while using only about 5.3% of the total model parameters, and it generalizes well to unseen neighboring factors.
