GATHER method improves zero-shot cell-type annotation with graph traversal

Researchers have developed GATHER, a new retrieval method designed for zero-shot cell-type annotation using gene expression data. This approach addresses the challenge of analyzing queries with numerous genes by identifying "convergence points" within biological knowledge graphs. These points represent synergistic gene combinations, allowing for more efficient evidence retrieval with fewer LLM calls compared to traditional methods. AI
