Reprompting: Automated Chain-of-Thought Prompt Inference Through Gibbs Sampling

Xu, Weijia, Banburski-Fahey, Andrzej, Jojic, Nebojsa

Understand

We introduce Reprompting, an iterative sampling algorithm that automatically learns the Chain-of-Thought (CoT) recipes for a given task without human intervention.

  • Through Gibbs sampling, Reprompting infers the CoT recipes that work consistently well for a set of training samples by iteratively sampling new recipes using previously sampled recipes as parent prompts to solve other training problems.
  • We conduct extensive experiments on 20 challenging reasoning tasks.
  • Results show that Reprompting outperforms human-written CoT prompts substantially by +9.4 points on average.
