NettetUMAP does offer significant improvements over algorithms like t-SNE for clustering. First, by preserving more global structure and creating meaningful separation between connected components of the manifold on which the data lies, UMAP offers more meaningful clusters. Second, because it supports arbitrary embedding dimensions, … NettetCells within the graph-based clusters determined above should co-localize on these dimension reduction plots. As input to the UMAP and tSNE, we suggest using the same PCs as input to the clustering analysis. ```{r tsne, fig.height=5, fig.width=7} # If you haven't installed UMAP, you can do so via reticulate::py_install(packages = "umap-learn")
