Several computational methods have been developed to construct single-cell pseudotime embeddings for extracting the temporal order of transcriptional cell states from time-series scRNA-seq datasets. However, existing methods suffer from low predictive accuracy, and this problem becomes even worse when we try to generalize to other data types such as scATAC-seq or microscopy images. To address this problem, we propose Sceptic, a support vector machine model for supervised pseudotime analysis. We demonstrate that Sceptic achieves significantly improved prediction power relative to state-of-the-art methods, and that Sceptic can be applied to a variety of single-cell data types, including single-nucleus image data.
已经开发了几种计算方法来构建单细胞伪时间嵌入,以便从时间序列单细胞RNA测序(scRNA-seq)数据集中提取转录细胞状态的时间顺序。然而,现有方法存在预测准确性低的问题,当我们试图推广到其他数据类型(如单细胞染色质可及性测序(scATAC-seq)或显微镜图像)时,这个问题会变得更加严重。为了解决这个问题,我们提出了Sceptic,一种用于监督伪时间分析的支持向量机模型。我们证明,相对于现有技术方法,Sceptic具有显著提高的预测能力,并且Sceptic可以应用于多种单细胞数据类型,包括单核图像数据。
