English(EN) ToPA: Block-wise Toeplitz Adaptation for Expressive and Efficient Fine-Tuning

新的ToPA方法使用块状Toeplitz矩阵进行高效模型微调

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-19 04:00

研究人员推出了一种新颖的参数高效微调（PEFT）方法ToPA，该方法利用块状Toeplitz矩阵。该方法旨在通过提供更具表达力和更稳定的参数化，同时不施加显式的秩或稀疏性约束，来克服现有PEFT技术的局限性，例如低秩和基于稀疏的方法。在21个NLP和CV数据集上的理论分析和经验评估证明了ToPA的有效性及其相比当前方法的更强表达力。 AI

影响引入了一种更具表达力和更稳定的微调方法，可以提高在各种AI任务中适应大型预训练模型的效率。

ToPA：面向表达高效微调的块状Toeplitz自适应

arXiv:2610.22883v1 Announce Type: new Abstract: Parameter-Efficient Fine-Tuning (PEFT) has emerged as a prevalent strategy for adapting large pre-trained models. Among PEFT techniques, reparameterization-based methods, particularly those that employ low-rank or sparsity structure…
