Active-Prompt

Chain-of-thought (CoT) methods rely on a fixed set of human-annotated exemplars. The problem with this is that the exemplars might not be the most effective examples for the different tasks. To address this, Diao et al., (2023) recently proposed a new prompting approach called Active-Prompt to adapt LLMs to different task-specific example prompts (annotated with human-designed CoT reasoning).

Below is an illustration of the approach. The first step is to query the LLM with or without a few CoT examples. k possible answers are generated for a set of training questions. An uncertainty metric is calculated based on the k answers (disagreement used). The most uncertain questions are selected for annotation by humans. The new annotated exemplars are then used to infer each question.
