Yuanbao-Reranker模型在文本重排序方面达到最先进水平

研究人员开发了Yuanbao-Reranker,这是一系列基于Qwen3骨干网络构建的密集重排序模型,有0.6B、4B和8B参数规模。这些模型专为搜索、推荐和RAG系统中的高精度文本重排序而设计。开发过程包括通过多阶段策展流程创建了一个包含275万个排序组的大规模数据集,并使用逐点相关性交叉熵和最小间隔铰链目标相结合的方式训练模型。Yuanbao-Reranker在包括中文、多语言、英文、长文档和代码检索在内的多个基准测试中均表现出最先进的性能,在每个参数级别上都优于现有基线。 AI

影响 为重排序性能设定了新的基准,有可能改进搜索和RAG系统。

    Yuanbao-Reranker:文档驱动的合成与偏好蒸馏用于文本重排序

    High-precision text reranking is a critical component in modern search, recommendation, and agentic retrieval-augmented generation (RAG) systems. We present Yuanbao-Reranker, a family of general-purpose dense rerankers spanning 0.6B, 4B, and 8B parameter scales built upon the Qwe…
