Fast Randomized Low-Rank Adaptation of Pre-trained Language Models with PAC Regularization (2024.findings-acl)
Copied to clipboard
| Challenge: | Low-rank adaptation (LoRA) is an efficient way to fine-tune large language models (LLMs) but its memory overhead restricts it to scale up when the model size increases. |
| Approach: | They propose a low-rank adaptation method which decomposes model weight updates into a pair of low-ranked projection matrices and incorporates a regularizer to improve generalization. |
| Outcome: | The proposed method achieves better performance under few-shot settings and similar performance to the SOTA low-rank adaptation methods. |
