Calibrating and Rotating: A Unified Framework for Weight Conditioning in PEFT
This paper introduces a novel framework for Parameter-Efficient Fine-Tuning (PEFT) called Calibrating and Rotating, which unifies and extends existing methods like LoRA and DoRA. It identifies Singular Value Entropy as the key driver behind DoRA's superior performance and reformulates DoRA into a more efficient weight conditioning method. The framework proposes two new techniques: Pre-Diag, for efficient pre-trained weight calibration, and SORA (Skewed Orthogonal Rotation Adaptation), for powerful, norm-preserving feature space transformations. Experiments demonstrate that Pre-Diag and SORA achieve superior performance and efficiency across NLP tasks compared to LoRA and DoRA.

Unveiling DoRA's Mechanism: Singular Value Entropy
The research identifies that DoRA's performance gains over LoRA stem from its ability to consistently increase the Singular Value Entropy of the weight update matrix. This promotes a more uniform distribution of update energy across features, mimicking the desirable behavior of full fine-tuning and preventing over-specialization.
DoRA Reformulated: Efficient Weight Conditioning
DoRA is reframed as a more efficient weight conditioning method, revealing its mechanism as modulating the main weight matrix with a lightweight, learnable matrix. This reformulation not only clarifies DoRA's impact on the singular value spectrum but also replaces its computationally intensive column-wise norm computation with efficient matrix multiplication.
Pre-Diag: Efficient Pre-Trained Weight Calibration
Pre-Diag is a novel method that applies a diagonal conditioning matrix directly to pre-trained weights *before* the LoRA update. This approach efficiently calibrates pre-trained weights, simplifies the gradient path, and reduces training time, leading to improved performance and efficiency.
SORA: Skewed Orthogonal Rotation Adaptation
SORA introduces a parameter-efficient orthogonal rotation matrix P (constructed as the exponential of a low-rank skew-symmetric matrix) applied after the calibrated LoRA update. This performs a powerful, norm-preserving transformation of the feature space, further refining feature interactions and boosting model performance with computational efficiency.
