299-单细胞嵌入评估的局限性与scGraph新指标

该文献探讨了准确评估单细胞生物学研究中使用的嵌入模型的挑战。为证明现有评估标准（如scIB）的局限性，研究人员设计了一个名为Islander的模型，该模型在现有指标上得分最高，但却产生了扭曲生物结构的“孤岛”状嵌入。针对这一不足，文章提出了一种新的互补评估指标，称为scGraph，旨在标记和纠正此类失真。scGraph通过评估跨批次数据中细胞相似性图谱的一致性来运作，重点是确保更广泛的生物学结构和连续的细胞关系得到保留。该研究强调，scGraph能够检测到现有指标（scIB）可能忽略的生物学结构完整性问题。最终，作者建议将scGraph与既有的度量标准结合使用，以提供一个更全面且具有生物学意义的评估框架。References:* Wang H, Leskovec J, Regev A.
