Efficient Fine-Tuning with LoRA: A Guide to Optimal Parameter Selection for Large Language Models new
Brave Search
Open
Choosing the correct value of rank and the layers of the neural network architecture to target during adaptation could decide the quality of the output from the fine-tuned model. QLoRA results in further memory savings while preserving the adaptation quality. Even when the fine-tuning is performed, there are several important engineering considerations to ensure the adapted model is deployed in the correct manner. In summary, a concise table indicating the different combinations of LoRA parameters attempted, text quality output and number of parameters updated when fine-tuning OpenLLaMA-3b-v2 for 3 epochs on 5000 observations on a single A100 is shown below.
