Description
Another interesting improvement idea for our LoRA implementation:
> LoRA+: Efficient Low Rank Adaptation of Large Model, [https://arxiv.org/abs/2402.12354](https://arxiv.org/abs/2402.12354)
In short, they propose different learning rates for matrices A and B to enhance feature learning, resulting in 1-2% performance gains and up to 2X faster finetuning without extra computational cost.
Of course, we would have to independently confirm before we add a feature like this.
