语义土匪揭示了大型语言模型(LLM)的探索偏见源于语言先验

研究人员引入了“语义土匪”的概念,以分析大型语言模型(LLM)在决策任务中如何探索和利用选项。该框架强调,LLM 的探索行为显著受到其语言预训练产生的语义先验的影响,而不仅仅是任务的正式结构。研究发现,语义信息丰富的标签会导致探索减少和利用增加,如果语义信息与实际奖励结构不匹配,这可能会产生不利影响。此外,LLM 对负奖励比对正奖励更倾向于探索,这表明其基于语言的训练中存在固有的偏见。 AI

影响 揭示了由于语言预训练导致的大型语言模型(LLM)决策中存在的固有偏见,影响了在现实世界应用中的可靠性。

    Semantic Bandits: In-Context Exploration-Exploitation is Biased by Semantic Priors

    arXiv:2608.16707v1 Announce Type: cross Abstract: Large language models (LLMs) are increasingly deployed as decision-making agents in settings that require sophisticated environmental exploration. However, existing work has raised questions about how LLMs actually balance explora…
