I hate to be that type of a guy, but this is the weirdest behaviour of UMAP I've ever seen. The data has 0 information other than the order of observations. It is literally 0-dimensional – one dot. Yet, look at the beautiful UMAP
I am giving a seminar discussing recent criticism of using UMAP in All of Us paper in Nature doi.org/10.1038/s41586…. I will compare peculiarities of UMAP for single cell biology vs. population genomics applications. Join if you are interested, scilifelab.se/event/is-umap-….
Biologists, stop putting UMAP plots in your papers!
UMAP is a powerful tool for exploratory data analysis, but without a clear understanding of how it works, it can easily lead to confusion and misinterpretation.
