Few-shot Calibration

Also called contextual calibration, calibrate before use.

Few-shot calibration corrects a model's systematic biases toward particular answers, such as the most frequent or most recent label in the examples, by adjusting output probabilities measured on a content-free input.

Description

Zhao et al. identified majority-label bias, recency bias, and common-token bias in few-shot prompting, and proposed contextual calibration, which estimates the bias from an input such as "N/A" and rescales predictions to neutralize it.
