"Clustering with UMAP: Why and How Connectivity Matters",Ayush Dalmia于2021年所写,原文参见doi.org/10.1145/1122445,探讨了针对聚类任务时,使用UMAP时节点连通性的重要性,其对聚类效果有一定的影响,更精细的连通性概念可以提供一个更好的效果。 摘要: 基于拓扑的降维方法,如t-SNE和UMAP,在高维数据中取得了越来...

Mugen-UMAP, a Python package, extends the application of UMAP to single-cell DNA sequencing data, focusing on the visualization and identification of cell clusters based on gene mutation information. By applying this tool to two different example single-cell WES datasets—one comprising 12 NSCLC pa...

UMAP clustering identified the components of the pathway for tRNA wobble uridine modification (Fig. 1c), which requires the URM1 pathway for 2-thiolation and the Elongator complex for side chain formation at U34 of tRNA15. The clustering revealed two additional members that are likely to link ...
