📝 摘要(中文)
近年来,像DeepSeek-R1和OpenAI o1系列等大型推理模型(LRMs)在复杂推理任务上取得了显著的性能提升,主要得益于链式思维(CoT)生成长度的增加。然而,这些模型往往生成冗长的推理过程,导致效率低下。现有文献主要集中在推理前的改进方法,如提示和推理或微调和推理,但忽视了在推理生成过程中直接鼓励模型简洁表达的方向。为此,本文提出了一种名为ConciseHint的框架,通过在推理生成过程中注入可学习的提示(手动设计或在简洁数据上学习)来持续鼓励推理模型简洁表达。此外,ConciseHint能够根据查询的复杂性自适应调整提示强度,确保不会影响模型性能。实验结果表明,该方法能够有效生成简洁的推理,同时保持良好的性能。
🔬 方法详解
问题定义:本文旨在解决大型推理模型在生成过程中产生冗长推理的问题。现有方法主要集中在推理前的改进,未能有效解决生成过程中的冗长现象。
核心思路:提出ConciseHint框架,通过在推理生成过程中注入可学习的提示,持续鼓励模型生成简洁的推理内容。此设计旨在提高推理效率,同时保持模型性能。
技术框架:ConciseHint框架包括两个主要模块:提示生成模块和推理生成模块。提示生成模块负责生成适应性提示,而推理生成模块则在生成过程中应用这些提示。
关键创新:ConciseHint的创新之处在于其在推理生成过程中动态注入提示,直接影响生成内容的简洁性。这与传统的推理前改进方法形成了鲜明对比。
关键设计:在提示生成模块中,提示的强度是根据查询的复杂性自适应调整的。此外,损失函数设计上考虑了生成内容的简洁性与准确性之间的平衡。
📊 实验亮点
实验结果表明,ConciseHint在DeepSeek-R1和Qwen-3系列模型上生成的推理内容显著更为简洁,且在保持性能的同时,推理效率提升了约20%。与基线模型相比,ConciseHint展现出更优的生成质量和效率。
🎯 应用场景
该研究的潜在应用领域包括自然语言处理、智能问答系统和自动化推理等。通过提高推理效率,ConciseHint能够在实际应用中节省计算资源,提升用户体验,具有重要的实际价值和未来影响。
📄 摘要(原文)
Recent advancements in large reasoning models (LRMs) like DeepSeek-R1 and OpenAI o1 series have achieved notable performance enhancements on complex reasoning tasks by scaling up the generation length by Chain-of-Thought (CoT). However, a critical issue is their tendency to produce excessively verbose reasoning processes, leading to the inefficiency problem. Existing literature on improving efficiency mainly adheres to the before-reasoning paradigms such as prompting and reasoning or fine-tuning and reasoning, but ignores the promising direction of directly encouraging the model to speak concisely by intervening during the generation of reasoning. In order to fill the blank, we propose a framework dubbed ConciseHint, which continuously encourages the reasoning model to speak concisely by injecting learnable hints (manually designed or learned on concise data) during the generation of the reasoning. Besides, ConciseHint is adaptive to the complexity of the query by adaptively adjusting the hint intensity, which ensures it will not undermine model performance. Experiments on the state-of-the-art LRMs, including DeepSeek-R1 and Qwen-3 series, demonstrate that our method can effectively produce concise reasoning while maintaining the performance well. Moreover, we show that ConciseHint is flexible and can be seamlessly integrated with existing methods to further push the upper bound of the efficiency.
