📝 摘要(中文)
通过链式思维(CoT)提示,大型语言模型(LLMs)在各种推理任务上取得了显著的性能。然而,大多数研究是在无噪声环境下进行评估的,LLMs在嘈杂环境下产生不准确结果的问题尚未得到充分研究。现有研究利用触发句子来鼓励LLMs关注相关信息,但效果有限。受互动CoT方法的启发,本文提出了一种新颖的提示方法R$^3$提示,旨在嘈杂环境下进行CoT推理。R$^3$提示通过与LLMs的互动进行关键句提取、变量声明和答案预测,体现了回顾、重述和解决的思维过程。实验表明,R$^3$提示在嘈杂环境下的五个推理任务中显著优于现有的CoT提示方法。
🔬 方法详解
问题定义:本文解决的是大型语言模型在嘈杂环境下推理时产生不准确结果的问题。现有方法主要依赖触发句子,但在复杂背景下效果有限。
核心思路:R$^3$提示方法通过与LLMs的互动,促进关键句提取、变量声明和答案预测,形成回顾、重述和解决的思维过程,从而提高推理的准确性。

📄 摘要(原文)
With the help of Chain-of-Thought (CoT) prompting, Large Language Models (LLMs) have achieved remarkable performance on various reasoning tasks. However, most of them have been evaluated under noise-free context and the dilemma for LLMs to produce inaccurate results under the noisy context has not been fully investigated. Existing studies utilize trigger sentences to encourage LLMs to concentrate on the relevant information but the trigger has limited effect on final answer prediction. Inspired by interactive CoT method, where intermediate reasoning steps are promoted by multiple rounds of interaction between users and LLMs, we propose a novel prompting method, namely R$^3$ prompting, for CoT reasoning under noisy context. Specifically, R$^3$ prompting interacts with LLMs to perform key sentence extraction, variable declaration and answer prediction, which corresponds to a thought process of reviewing, rephrasing and resolving. The responses generated at the last interaction will perform as hints to guide toward the responses of the next interaction. Our experiments show that R$^3$ prompting significantly outperforms existing CoT prompting methods on five reasoning tasks under noisy context. With GPT-3.5-turbo, we observe 3.7% accuracy improvement on average on the reasoning tasks under noisy context compared to the most competitive prompting baseline. More analyses and ablation studies show the robustness and generalization of R$^3$ prompting method in solving reasoning tasks in LLMs under noisy context.
