研究人员开发了一种名为置换不变微调（PI-FT）的新微调方法，以提高结构化元数据的检索准确性。传统方法将元数据字段序列化为字符串，导致检索质量依赖于字段顺序。PI-FT通过在微调过程中随机化字段顺序来缓解此问题，显著降低了字段顺序变化时的性能下降。该方法在DevDataBench基准上进行了测试，性能优于text-embedding-3-large等强大基线，并在低资源语言中表现出特别的有效性。 AI

We study retrieval over catalogs of structured metadata, where each record is a small schema whose fields answer different kinds of query. Embedding a record with a text encoder first serializes its fields into a string, which forces a choice of field order. We show this choice, …
