研究人员开发了GATHER，一种用于使用基因表达数据进行零样本细胞类型注释的新型检索方法。该方法通过在生物知识图谱中识别“收敛点”来解决分析具有大量基因的查询的挑战。这些点代表协同基因组合，与传统方法相比，通过更少的LLM调用即可实现更有效的证据检索。 AI
影响 该方法可以通过优化LLM的使用，显著降低基于基因的细胞类型注释的计算成本。

GATHER：面向收敛的超实体检索用于零样本细胞类型注释
Zero-shot single-cell cell-type annotation aims to determine a cell's type from a given set of expressed genes without any training. Existing knowledge-graph-based RAG approaches retrieve evidence by expanding from source entities and relying on iterative LLM reasoning. However, …
