Machine Learning
Last updated: April 4, 2025

Definition

An efficient fine-tuning method combining quantization and LoRA for LLMs, reducing memory/compute needs.

Detailed Explanation

An efficient fine-tuning technique for large language models that combines quantization (reducing numerical precision, e.g., to 4-bit) with Low-Rank Adaptation (LoRA) to drastically reduce memory and computational requirements while maintaining performance.

Use Cases

Fine-tuning large language models on consumer hardware, reducing deployment costs, enabling customization of massive models with limited resources.
