AI总结:
本文综述了大型语言模型中的幻觉问题,提出了幻觉现象与评估基准的分类体系,分析了现有的检测与缓解方法,并探讨了未来研究方向。
摘要:
尽管大型语言模型(LLMs)在一系列下游任务中展现了卓越能力,但一个重大隐患是其产生幻觉的倾向:LLMs偶尔会生成偏离用户输入、与先前生成的上下文矛盾,或与既定世界知识不符的内容。这一现象对LLMs在现实场景中的可靠性构成了巨大挑战。本文综述了近期在幻觉检测、解释和缓解方面的努力,并重点关注LLMs带来的独特挑战。我们提出了LLM幻觉现象和评估基准的分类体系,分析了旨在缓解LLM幻觉的现有方法,并探讨了未来研究的潜在方向。
英文摘要:
While large language models (LLMs) have demonstrated remarkable capabilities across a range of downstream tasks, a significant concern revolves around their propensity to exhibit hallucinations: LLMs occasionally generate content that diverges from the user input, contradicts previously generated context, or misaligns with established world knowledge. This phenomenon poses a substantial challenge to the reliability of LLMs in real-world scenarios. In this paper, we survey recent efforts on the detection, explanation, and mitigation of hallucination, with an emphasis on the unique challenges posed by LLMs. We present taxonomies of the LLM hallucination phenomena and evaluation benchmarks, analyze existing approaches aiming at mitigating LLM hallucination, and discuss potential directions for future research.
