System One 决策模型在重排任务上并不优于重排微调

一篇新发表在 arXiv 上的研究调查了在信息检索任务中,作为重排器的“System One”模型(也称为决策模型)的有效性。该研究使用不同的 Qwen 主干模型和基准数据集,将这些模型与传统的重排微调和零样本方法进行了比较。研究结果表明,与标准的重排微调相比,决策微调并不能带来更好的重排性能,后者在不同参数规模下始终优于决策模型。 AI

影响 这项研究表明,对于重排任务,System One 模型传统的微调方法比专注于决策的微调更有效。

    System One模型并非更优的重排器

    arXiv:2610.32318v1 Announce Type: new Abstract: System One models, or decision models, answer a question about an input with a calibrated probability instead of generated text. Within weeks of the first release, in September 2026, they were used as rerankers. We test whether the …
