Q

QLoRA

Quantized Low-Rank Adaptation — combines LoRA with quantization to further reduce memory requirements for fine-tuning. It quantizes the base model to 4-bit precision while training LoRA adapters in higher precision.

Machine Learning

Quantization

The process of reducing the precision of a model's numerical weights (e.g., from 32-bit to 8-bit or 4-bit), making the model smaller and faster while accepting a small trade-off in accuracy.

Artificial Intelligence

Quantization-Aware Training

Training a model while simulating the effects of quantization, so the model learns to maintain accuracy even when weights are later reduced to lower precision.

Machine Learning

Question Answering

An NLP task where the model provides direct answers to questions, either from a given context passage (extractive QA) or from general knowledge (open-domain QA).
