Chain-of-thought (CoT) prompting can guide language models to engage in complex multi-step reasoning. The quality of provided demonstrations significantly impacts the success of downstream inference tasks. While existing automated methods prioritize accuracy and semantics in these demonstrations, we show that the underlying reasoning patterns play a more crucial role in such tasks. In this paper, we propose Pattern-Aware CoT, a prompting method that considers the diversity of demonstration patterns. By incorporating patterns such as step length and reasoning process within intermediate steps, PA-CoT effectively mitigates the issue of bias induced by demonstrations and enables better generalization to diverse scenarios. We conduct experiments on nine reasoning benchmark tasks using two open-source LLMs. The results show that our method substantially enhances reasoning performance and exhibits robustness to errors. The code will be made publicly available.

链式思维提示可以引导语言模型进行复杂的多步推理。我们提出了一种考虑演示模式多样性的提示方法，通过在中间步骤中结合步长和推理过程等模式，有效地缓解由演示引起的偏差问题并实现对不同场景的更好泛化。我们在两个开源 LLM 模型上进行了九个推理基准任务的实验，结果表明我们的方法大大提高了推理性能，并且对错误表现出鲁棒性。代码将公开提供。
