AI总结:

本文基于归纳逻辑编程基准评估多个最先进大语言模型的推理能力,发现其在IID和OOD测试上的性能与泛化能力均显著弱于规模更小的神经程序归纳系统。

摘要:

大语言模型(LLMs)通过在大量下游任务上取得最先进性能,已经彻底改变了许多领域(例如自然语言处理、软件工程等)。为了实现鲁棒且通用的人工智能,人们对研究大语言模型的推理能力产生了浓厚的兴趣。然而,以往工作采用的文本和数值推理基准相当浅显和简单,仅凭在这些基准上取得正向结果很难得出大语言模型具备强大推理能力的结论。近期已有研究通过评估大语言模型在强化学习基准上的表现,证明它们在解决需要常识规划的序列决策问题时表现不佳。在本工作中,我们基于归纳逻辑编程(ILP)基准对多个最先进大语言模型的推理能力进行了深入评估。该基准被广泛认为是评估逻辑程序归纳/合成系统的代表性且具有挑战性的度量标准,因为它要求归纳出严格的因果逻辑,从而在独立同分布(IID)和分布外(OOD)测试样本上实现稳健的演绎推理。我们的评估表明,与模型规模小得多的神经程序归纳系统相比,最先进的大语言模型在推理能力方面表现明显更差,无论使用自然语言提示还是真值矩阵提示,其性能和泛化能力都低得多。

英文摘要:

Large language models (LLMs) have revolutionized many areas (e.g. natural language processing, software engineering, etc.) by achieving state-of-the-art performance on extensive downstream tasks. Aiming to achieve robust and general artificial intelligence, there has been a surge of interest in investigating the reasoning ability of the LLMs. Whereas the textual and numerical reasoning benchmarks adopted by previous works are rather shallow and simple, it is hard to conclude that the LLMs possess strong reasoning ability by merely achieving positive results on these benchmarks. Recent efforts have demonstrated that the LLMs are poor at solving sequential decision-making problems that require common-sense planning by evaluating their performance on the reinforcement learning benchmarks. In this work, we conduct an in-depth assessment of several state-of-the-art LLMs' reasoning ability based on the inductive logic programming (ILP) benchmark, which is broadly recognized as a representative and challenging measurement for evaluating logic program induction/synthesis systems as it requires inducing strict cause-effect logic to achieve robust deduction on independent and identically distributed (IID) and out-of-distribution (OOD) test samples. Our evaluations illustrate that compared with the neural program induction systems which are much smaller in model size, the state-of-the-art LLMs are much poorer in terms of reasoning ability by achieving much lower performance and generalization using either natural language prompting or truth-value matrix prompting.
