AI总结:

研究探讨了如何通过监督微调使AI处理例外,发现使用人类解释的微调能显著提升模型决策能力,揭示了对齐人类判断需明确训练决策过程而非仅决策结果。

摘要:

大型语言模型(LLMs)最初为生成式AI开发,现已演变为代理AI系统,在复杂现实环境中做决策。然而,尽管其生成能力已得到充分证明,其决策过程仍不清晰。尤其在测试目标决策时,如模型如何处理例外(合同固有不完整性的关键挑战)尤为明显。本文证明,即使优秀的推理模型也会因严格遵守政策而偏离人类判断,即使这种遵守不切实际、次优或甚至有害。我们评估了三种调整AI代理处理例外的方法:伦理框架提示、推理链和监督微调。发现尽管伦理框架提示失败,推理链提示仅提供小幅改进,而监督微调(特别是使用人类解释)产生显著结果。令人惊讶的是,在实验中,监督微调使模型能将人类般的决策泛化到新场景,展示了跨情境的人类对齐决策转移学习。进一步发现,使用解释而非仅标签的微调对对齐至关重要,表明对齐LLMs需明确训练决策过程而非仅决策结果。这些发现突显了解决LLMs在处理例外方面的不足,以指导代理AI的发展,使其能有效对齐人类判断并适应新情境。

英文摘要:

Large language models (LLMs), initially developed for generative AI, are now evolving into agentic AI systems, which make decisions in complex, real-world contexts. Unfortunately, while their generative capabilities are well-documented, their decision-making processes remain poorly understood. This is particularly evident when testing targeted decision-making: for instance, how models handle exceptions, a critical and challenging aspect of decision-making made relevant by the inherent incompleteness of contracts. Here we demonstrate that LLMs, even ones that excel at reasoning, deviate significantly from human judgments because they adhere strictly to policies, even when such adherence is impractical, suboptimal, or even counterproductive. We then evaluate three approaches to tuning AI agents to handle exceptions: ethical framework prompting, chain-of-thought reasoning, and supervised fine-tuning. We find that while ethical framework prompting fails and chain-of-thought prompting provides only slight improvements, supervised fine-tuning - specifically with human explanations - yields markedly better results. Surprisingly, in our experiments, supervised fine-tuning even enabled models to generalize human-like decision-making to novel scenarios, demonstrating transfer learning of human-aligned decision-making across contexts. Furthermore, fine-tuning with explanations, not just labels, was critical for alignment, suggesting that aligning LLMs with human judgment requires explicit training on how decisions are made, not just which decisions are made. These findings highlight the need to address LLMs' shortcomings in handling exceptions in order to guide the development of agentic AI toward models that can effectively align with human judgment and simultaneously adapt to novel contexts.
