AI总结:

本文指出LLMs因依赖词嵌入统计模式而本质上不可信,易产生幻觉和错误信息,并提出结合事实库与逻辑编程有望构建可信LLMs。

摘要:

大语言模型(LLMs)在自然语言处理方面取得了显著进展,但其底层机制常常被误解。尽管LLMs表现出连贯的回答和看似推理的行为,它们依赖的是词嵌入中的统计模式,而非真正的认知过程。这导致了诸如“幻觉”和错误信息等脆弱性。本文认为,当前的LLM架构因其依赖词嵌入向量顺序模式的相关性而本质上不可信。然而,将基于生成式Transformer的模型与事实库和逻辑编程语言相结合的持续研究,可能推动可信LLMs的发展,使其能够基于给定事实生成陈述并解释其自我推理过程。

英文摘要:

Large Language Models (LLMs) have made significant advances in natural language processing, but their underlying mechanisms are often misunderstood. Despite exhibiting coherent answers and apparent reasoning behaviors, LLMs rely on statistical patterns in word embeddings rather than true cognitive processes. This leads to vulnerabilities such as "hallucination" and misinformation. The paper argues that current LLM architectures are inherently untrustworthy due to their reliance on correlations of sequential patterns of word embedding vectors. However, ongoing research into combining generative transformer-based models with fact bases and logic programming languages may lead to the development of trustworthy LLMs capable of generating statements based on given truth and explaining their self-reasoning process.
