Fireworks AI suggests LoRA optimization tests before full fine-tuning

Fireworks AI suggests that if LoRA (Low-Rank Adaptation) is not performing optimally, users should first consider inexpensive tests before resorting to full parameter fine-tuning. The company conducted three tests focusing on data coverage, optimization, and rank to evaluate if these methods could bridge the performance gap between LoRA and full fine-tuning, with varying success.

    If LoRA is underperforming, don't reach for more expensive full parameter fine-tuning right away.

    If LoRA is underperforming, don't reach for more expensive full parameter fine-tuning right away. We ran three cheap tests (data coverage, optimization, rank) to see if we could close the gap between LoRA and FullFT. Sometimes we could, sometimes we couldn't. https://t.co/29iCx…
