Chroma 技术报告:嵌入向量适配器可将检索准确率提升最高 70%
Chroma 发布技术报告,提出在嵌入模型输出后加一个线性变换“适配器”,仅用少至 1,500 条标注查询-文档对训练、且只作用于查询嵌入,即可让检索准确率较原始预训练嵌入模型提升最高 70%。负样本可直接从非相关文档中随机采样,大幅降低标注成本;该方法对约 10,000 条嵌入规模的小型集合尤为适用,代码已在 GitHub 开源。

arning processes more computationally tractable, but also enable the discovery of hidden connections and similarities that might be obscured in the original representation. By leveraging pre-trained embeddings and fine-tuning them with task-specific data, we can create models that are more accurate and require less training time compared to learning from scratch. This approach has been particularly successful in natural language processing tasks, such as sentiment analysis, named entity recognit
