What is Calibration data?
Source: local-llm.net/glossary
A representative dataset used during quantization (in GPTQ, AWQ, and EXL2) to measure the impact of weight compression on model outputs. The quantization algorithm uses this data to minimize the difference between the full-precision and quantized model. Typically a few hundred examples from a general text corpus.
