Retraction-Free Optimization over the Stiefel Manifold for the LoRA Fine-Tuning

Yuan Zhang, Jiang Hu, Zhijian Lai +2

Optimization over the Stiefel manifold plays a significant role in various machine learning tasks. Existing methods either use the retraction operators, requiring costly orthonorma…

Learning the mapping $x \mapsto \sum_{i = 1}^{d} x_{i}^{2}$ : the cost of finding the needle in a haystack

Jiefu Zhang, Leonardo Zepeda-Núñez, Yuan Yao +1

The task of using machine learning to approximate the mapping $x \mapsto \sum_{i = 1}^{d} x_{i}^{2}$ with $x_{i} \in [- 1, 1]$ seems to be a trivial one. Given the knowledge of the separa…
