English(EN) BayesPO: Bayesian Prompt Optimization via Parallel-Tempered Gradient-Guided Discrete MCMC

BayesPO框架使用贝叶斯采样进行LLM提示优化

作者 PulseAugur 编辑部 · [1 个来源] · 2026-07-20 04:00

研究人员开发了BayesPO，一个用于优化大型语言模型提示的新框架，且无需更改模型参数。该方法将提示优化视为贝叶斯后验采样，将特定任务的奖励与语言模型先验相结合，以指导离散马尔可夫链蒙特卡洛提案。使用Qwen2.5模型的实验表明，BayesPO可以发现语义上有意义的提示，并提高诊断任务的准确性，尽管它目前面临计算成本和潜在过拟合的限制。 AI

影响这种原则性的提示优化方法可能无需参数更新即可实现更高效、更有效的LLM微调。

BayesPO：通过并行退火梯度引导离散MCMC进行贝叶斯提示优化

arXiv:2607.16001v1 Announce Type: new Abstract: Prompt optimization adapts large language models (LLMs) without updating model parameters, but many automatic prompt optimizers remain heuristic search procedures over candidate instructions. This paper studies prompt optimization a…
