AI总结:

本研究提出Ordered CommonGen基准,通过有序覆盖率同时评估LLMs的组合泛化与指令遵循能力,发现LLMs存在顺序偏见且最强者覆盖率仅约75%,需改进。

摘要:

在诸如CommonGen等生成式常识推理任务中,生成式大语言模型(LLMs)会组合包含所有给定概念的句子。然而,当关注指令遵循能力时,如果提示指定了概念顺序,LLMs必须生成遵循该指定顺序的句子。为解决此问题,我们提出了Ordered CommonGen,一个旨在评估LLMs组合泛化与指令遵循能力的基准。该基准通过衡量有序覆盖率来评估概念是否按指定顺序生成,从而能够同时评估这两种能力。我们使用36个LLMs进行了全面分析,发现尽管LLMs普遍理解指令意图,但对特定概念顺序模式的偏见往往导致低多样性输出,甚至在概念顺序改变时产生相同结果。此外,即使最遵循指令的LLM也仅达到约75%的有序覆盖率,凸显了在指令遵循和组合泛化能力方面改进的必要性。

英文摘要:

In generative commonsense reasoning tasks such as CommonGen, generative large language models (LLMs) compose sentences that include all given concepts. However, when focusing on instruction-following capabilities, if a prompt specifies a concept order, LLMs must generate sentences that adhere to the specified order. To address this, we propose Ordered CommonGen, a benchmark designed to evaluate the compositional generalization and instruction-following abilities of LLMs. This benchmark measures ordered coverage to assess whether concepts are generated in the specified order, enabling a simultaneous evaluation of both abilities. We conducted a comprehensive analysis using 36 LLMs and found that, while LLMs generally understand the intent of instructions, biases toward specific concept order patterns often lead to low-diversity outputs or identical results even when the concept order is altered. Moreover, even the most instruction-compliant LLM achieved only about 75% ordered coverage, highlighting the need for improvements in both instruction-following and compositional generalization capabilities.
