📝 摘要(中文)

大语言模型(LLMs)在处理推理任务方面表现出色,但现有方法普遍采用一刀切的策略,未能根据任务复杂性灵活调整求解策略。为了解决这一问题,本文提出了自适应求解框架(AS),能够动态调整求解策略以适应不同问题,从而优化计算资源的分配。该框架包含初始评估模块和适应模块,通过多种适应策略的协同作用,显著降低计算消耗并提升性能。实验结果表明,该方法在复杂推理基准上可将API成本降低至85%,同时在相同成本下提高准确率达4.5%。

🔬 方法详解

问题定义:本文旨在解决大语言模型在推理任务中采用固定求解策略所带来的效率低下和性能不佳的问题。现有方法未能根据任务复杂性灵活调整,导致计算资源浪费。

核心思路:提出的自适应求解框架通过动态调整求解策略,能够根据不同问题的复杂性灵活分配计算资源,从而提高效率和准确性。

技术框架:该框架主要由两个模块组成:初始评估模块和适应模块。初始评估模块用于评估当前解的可靠性,如果解不可靠,则激活适应模块,采用多种适应策略进行协同调整。

关键创新:最重要的创新在于动态适应策略的引入,使得求解过程能够根据实时反馈进行调整,与传统固定策略方法形成鲜明对比。

关键设计:在设计上,初始评估模块通过答案一致性评估解的可靠性,适应模块则结合多种适应策略进行优化,确保在不同复杂度问题上都能有效运作。具体的参数设置和损失函数设计在论文中详细描述。

📄 摘要(原文)

Large Language Models (LLMs) demonstrate impressive ability in handling reasoning tasks. However, unlike humans who can instinctively adapt their problem-solving strategies to the complexity of task, most LLM-based methods adopt a one-size-fits-all approach. These methods employ consistent models, sample sizes, prompting methods and levels of problem decomposition, regardless of the problem complexity. The inflexibility of these methods can bring unnecessary computational overhead or sub-optimal performance. To address this limitation, we introduce an Adaptive-Solver (AS) framework tha dynamically adapts solving strategies to suit various problems, enabling the flexible allocation of test-time computational resources. The framework functions with two primary modules. The initial evaluation module assesses the reliability of the current solution using answer consistency. If the solution is deemed unreliable, the subsequent adaptation module comes into play. Within this module, various types of adaptation strategies are employed collaboratively. Through such dynamic and multi-faceted adaptations, our framework can help reduce computational consumption and improve performance. Experimental results from complex reasoning benchmarks reveal that our method can significantly reduce API costs (up to 85%) while maintaining original performance. Alternatively, it achieves up to 4.5% higher accuracy compared to the baselines at the same cost. The code and dataset are available at https://github.com/john1226966735/Adaptive-Solver.
