English(EN) $S^3$: Spectral Null-Space Swap Makes Reasoning Models Efficient

$S^3$方法将LLM推理效率提高27%，同时提高准确性

作者 PulseAugur 编辑部 · [1 个来源] · 2026-09-29 16:44

研究人员开发了一种名为谱零空间交换（$S^3$）的新方法，以提高使用思维链（Chain-of-Thought）推理的大型语言模型（LLMs）的效率。该技术发现，核心推理能力存在于模型主导奇异方向零空间内的特定权重分量中。通过操纵这个零空间分量，$S^3$可以在不牺牲准确性的情况下，显著降低与推理相关的代币成本。在各种模型架构和推理领域的评估显示，推理代币开销平均减少了27.4%，整体任务准确性提高了1.0个百分点。 AI

影响该方法可能导致更具成本效益的推理能力LLM的部署，从而可能加速其在资源受限环境中的应用。

$S^3$：谱零空间交换使推理模型更高效

LLMs trained with Chain-of-thought excel in reasoning capability, but often come with excessive token cost. We find that the core of reasoning capacity lies in the Thinking model's weight component within the null space of a projection defined by the corresponding Non-thinking mo…
