Overcoming Memory Limitations with Advanced Techniques
In this informative tutorial, we delve into the intricacies of fine-tuning the LLaMA 2 model to enhance its capabilities. We explore innovative techniques such as QLoRA PEFT and SFT, which effectively address memory constraints and enable seamless fine-tuning on your own datasets.
QLoRA PEFT: Quantization for Memory Efficiency
QLoRA PEFT (Quantized Low-Rank Matrix Factorization with PEFT) is a groundbreaking technique that exploits low-rank factorization and quantization to significantly reduce memory consumption during fine-tuning. This approach factorizes weight matrices into low-rank components and quantizes the resulting factors, resulting in substantial memory savings without compromising model accuracy.
SFT: Sparse Fine-tuning for Scalability
Sparse Fine-tuning (SFT) is another innovative technique that leverages the sparsity of natural language data to enable efficient fine-tuning on large-scale datasets. SFT leverages a sparse representation of the input data, reducing both memory usage and computational costs. This technique allows for the fine-tuning of LLaMA 2 on datasets that would otherwise be computationally intractable.
