I am gong thru the official tutorial. I have 256 GB ram so that should be fine. It just dies in 1 sec just after starting the HDBSCAN part. a.) CODE = Official Tutorial, Official dataset clusterable_embedding = umap.UMAP( n_neighbors=30,...
Hi, when using tSNE, it is usually not recommended to perform clustering on the "reduced space" with algorithms such as k-means or DBSCAN (and HDBSCAN?) because the dimensionality reduction applied by tSNE doesn't keep properties like re...

You can use UMAP as a general purpose dimension reduction technique as a preliminary step to other machine learning tasks. With a little care it partners well with thehdbscanclustering library (for more details please seeUsing UMAP for Clustering). ...
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 ...
Identify clusters of cells by a shared nearest neighbor (SNN) modularity optimization based clustering algorithm. First calculate k-nearest neighbors and construct the SNN graph. Then optimize the modularity function to determine clusters. For a full description of the algorithms, see Waltman and van...
