Therefore, my prediction is that UMAP is just the beginning, and there going to be many more, and possibly better, dimension reduction techniques appearing in the Single Cell Genomics research area in the nearest future. Larger values result in more global views of the manifold. UMAP is a general purpose manifold learning and dimension reduction algorithm. In the example below, we see how easy it is to use UMAP as a drop-in replacement for scikit-learn&#39;s manifold.
