Thus you can have more confidence in the results of clustering UMAP than t-SNE, but I would still strongly encourage actual analysis of the clusters. If you want evidence that this can work, using HDBSCAN on a UMAP embedding of the MNIST digits dataset (with suitable parameter choices for ...

In this section we will use the methodology of PLS estimation of variance explained developed in the previous section. Again, we will use the same reasoning: since UMAP gives some sort ofapproximationof the original dataX, and people even runclustering on 2D UMAPfor discovering cell types in ...
A benchmarking analysis on single-cell RNA-seq and mass cytometry data reveals the best-performing technique for dimensionality reduction. Advances in single-cell technologies have enabled high-resolution dissection of tissue composition. Several tools f

Here are some additional tools we have added to our implementation: 1) The ability to detect clusters in the low-dimensional output of UMAP. As clustering method, we invoke either DBM (described athttps://www.hindawi.com/journals/abi/2009/686759/) or DBSCAN (built in to MATLAB R2019...
As another note in my experience the UMAP/analysis done by cell ranger on my datasets has never seemed that good (as result of automated nature of it likely) and fact that you are not performing much filtering of the dataset before analysis/clustering so overall I'm not sure how much weig...
