📝 摘要(中文)
在过去一年,自然语言生成(NLG)领域经历了快速发展,主要得益于大型语言模型(LLMs)的引入。这些模型在自然语言处理和生成的多个领域表现出色,但在特定领域任务如释义生成中面临挑战。由于参数量庞大,LLMs在商业硬件上的操作困难,推理时间长,导致生产成本高。本文通过应用序列级知识蒸馏方法,开发了三种不同的释义生成模型,能够保持LLM生成释义的质量,同时实现更快的推理时间和多样化的释义生成。人类评估显示,尽管模型体积缩小了1000倍,但性能仅下降4%。该研究为NLG领域提供了更高效、经济的释义生成解决方案。

📄 摘要(原文)
Over the past year, the field of Natural Language Generation (NLG) has experienced an exponential surge, largely due to the introduction of Large Language Models (LLMs). These models have exhibited the most effective performance in a range of domains within the Natural Language Processing and Generation domains. However, their application in domain-specific tasks, such as paraphrasing, presents significant challenges. The extensive number of parameters makes them difficult to operate on commercial hardware, and they require substantial time for inference, leading to high costs in a production setting. In this study, we tackle these obstacles by employing LLMs to develop three distinct models for the paraphrasing field, applying a method referred to as sequence-level knowledge distillation. These distilled models are capable of maintaining the quality of paraphrases generated by the LLM. They demonstrate faster inference times and the ability to generate diverse paraphrases of comparable quality. A notable characteristic of these models is their ability to exhibit syntactic diversity while also preserving lexical diversity, features previously uncommon due to existing data quality issues in datasets and not typically observed in neural-based approaches. Human evaluation of our models shows that there is only a 4% drop in performance compared to the LLM teacher model used in the distillation process, despite being 1000 times smaller. This research provides a significant contribution to the NLG field, offering a more efficient and cost-effective solution for paraphrasing tasks.
