AI总结:

F-Eval提出双语评估基准,涵盖表达、常识与逻辑,通过新评估方法替代API评分,在13个LLM上验证了更高相关性和区分度。

摘要:

大型语言模型(LLMs)因其前所未有的性能而受到广泛关注,导致越来越多的研究对LLMs进行评估。然而,这些评估基准仅限于评估指令遵循能力,忽视了预训练阶段涌现的基础能力。以往的主观评估方法主要依赖API模型进行评分。然而,在缺乏参考的情况下,大型模型在辨别细微差异方面表现出有限的能力。为弥补这一差距,我们提出了F-Eval,一个双语评估基准,用于评估基础能力,包括表达能力、常识和逻辑。F-Eval中的任务包括多项选择客观任务、开放式客观任务、基于参考的主观任务和无参考的主观任务。对于无参考的主观任务,我们设计了新的评估方法,作为API模型评分的替代方案。我们对13个先进的LLMs进行了评估。结果表明,我们的评估方法相比其他评估者具有更高的相关系数和更大的区分度。此外,我们讨论了不同模型规模、维度和归一化方法的影响。我们期望F-Eval能促进对LLMs基础能力的研究。

英文摘要:

Large language models (LLMs) garner significant attention for their unprecedented performance, leading to an increasing number of researches evaluating LLMs. However, these evaluation benchmarks are limited to assessing the instruction-following capabilities, overlooking the fundamental abilities that emerge during the pre-training stage. Previous subjective evaluation methods mainly reply on scoring by API models. However, in the absence of references, large models have shown limited ability to discern subtle differences. To bridge the gap, we propose F-Eval, a bilingual evaluation benchmark to evaluate the fundamental abilities, including expression, commonsense and logic. The tasks in F-Eval include multi-choice objective tasks, open-ended objective tasks, reference-based subjective tasks and reference-free subjective tasks. For reference-free subjective tasks, we devise new evaluation methods, serving as alternatives to scoring by API models. We conduct evaluations on 13 advanced LLMs. Results show that our evaluation methods show higher correlation coefficients and larger distinction than other evaluators. Additionally, we discuss the influence of different model sizes, dimensions, and normalization methods. We anticipate that F-Eval will facilitate the study of LLMs' fundamental abilities.
