Microsoft, Beihang release MoRA, an efficient LLM fine-tuning technique

I don’t see the added value of posting a venturebeat link rather than linking directly to arxiv: <a href="https:&#x2F;&#x2F;arxiv.org&#x2F;abs&#x2F;2405.12130v1" rel="nofollow">https:&#x2F;&#x2F;arxiv.org&#x2F;abs&#x2F;2405.12130v1</a>

I don&#x27;t understand the paper. It doesn&#x27;t seem to be written very well. Are they replacing a low-rank adaptation with a banded matrix? And what is the point of the rotations?
