(1) Our insights (paper, in progress):

According to the traditional statistical learning viewpoint, performance can be defined by the sum of optimization error and generalization error. In (generalization, storage-friendly), we give Theorem 1 (Information-theoretic genralization bounds), showing that with the same $r$ value, fine-tuning $\mathbf{W}_q,\mathbf{W}_v$ consistently achieves results comparable to or even surpassing those of fine-tuning $\mathbf{W}_q,\mathbf{W}_k,\mathbf{W}_v$. This reduces the number of parameters for the same $r$, while improving generalization bounds and potentially providing memory benefits. In (optimization, time-friendly), we discuss the learning dynamics in fine-tuning attention mechanism, and we illustrate Theorem 2 that the feature learning of attention mechanism is efficient when the learning rate for $\mathbf{W}_v$ should be generally much larger than that of $\mathbf{W}_q,\mathbf{W}_k$ in fine-tuning. Building on our experimental and theoretical insights, one can develop new algorithms to improve the effectiveness (e.g., storage, and time) of fine-tuning.

(2) Target:

$\text{\textcolor{blue}{This project conducts comprehensive benchmarking of the following 10+ efficient fine-tuning methods.}}$

Notably, our proposed approach maintains orthogonal compatibility and can be synergistically combined with any of these methods.
