基于多轮问询的大语言模型幻觉识别和减弱方法的研究
首发时间:2024-06-19
摘要:大语言模型(Large Language Models, LLMs)在生成文本时,有时会产生与事实不符或逻辑不一致的内容,这种现象被称为"幻觉"(hallucination)。本文首先详细介绍了幻觉现象的定义、产生原因及其在不同应用场景中的表现,特别是代码编辑中的幻觉问题。幻觉现象不仅影响了文本生成的可靠性,还可能对实际应用造成严重影响。 为了应对这一挑战,本文设计并提出了一种基于多轮问询和逆向检查的幻觉识别方法--GPT-HM(Hallucination Mitigation)。该方法通过多轮问询的策略不断对模型生成的内容进行验证,并结合逆向检查机制,从多个角度对生成内容的真实性和一致性进行评估。GPT-HM的核心在于利用多轮交互和逆向思维,尽可能减少模型生成幻觉的概率。 在实验部分,本文选择了两个典型领域进行测试和验证。首先,在自然语言处理领域,我们使用TruthfulQA数据集进行了广泛的实验。结果表明,GPT-HM在提升模型生成内容的真实性和准确性方面表现出色。其次,在软件工程领域,我们将GPT-HM应用于Linux操作系统中的自动化代码编辑任务中,结果显示该方法能够显著减少代码生成过程中的幻觉现象,提高代码的正确性和执行效率。 最后,本文对研究成果进行了总结,指出了当前方法的优势和不足,并对未来研究方向提出了建议。本文的研究成果不仅为幻觉现象的识别和减弱提供了新的解决方案,也为大语言模型在实际应用中的可靠性提升提供了重要参考。

Research on Recognizing and Mitigating Hallucinations in Large Language Models Based on Multi-Turns Inquiries
Abstract:Large Language Models (LLMs) sometimes generate text that is factually incorrect or logically inconsistent, a phenomenon known as "hallucination." This paper provides a detailed introduction to the definition, causes, and manifestations of hallucinations in various application scenarios, with a particular focus on hallucinations in code editing. Hallucinations not only affect the reliability of generated text but can also cause serious issues in practical applications. To address this challenge, this paper proposes a method for hallucination identification and mitigation based on multi-round inquiry and reverse checking, called GPT-HM (Hallucination Mitigation). This method continuously verifies the content generated by the model through a strategy of multi-round inquiry and evaluates the truthfulness and consistency of the content from multiple perspectives using reverse checking mechanisms. The core of GPT-HM lies in utilizing multi-round interactions and reverse thinking to minimize the probability of hallucinations in model-generated content. In the experimental section, we conducted extensive tests and validations in two typical domains. First, in the field of natural language processing, we used the TruthfulQA dataset to conduct experiments. The results demonstrate that GPT-HM significantly improves the truthfulness and accuracy of the generated content. Second, in the field of software engineering, we applied GPT-HM to the task of automated code editing in the Linux operating system. The results show that this method effectively reduces hallucinations in code generation, improving the correctness and execution efficiency of the code. Finally, this paper summarizes the research findings, highlighting the advantages and limitations of the current method, and proposes directions for future research. The results of this study not only provide a new solution for the identification and mitigation of hallucinations but also offer important references for improving the reliability of LLMs in practical applications.)
