If you're interested in getting a feel for how these work, I'd suggest running each of the methods on the data in this section. WebOut of the box, UMAP with precomputed_knn supports creating reproducible results. This works inexactly the same way as regular UMAP, where, the user can set a random seed state to ensure that results can be reproduced exactly. However, some important considerations must be taken into account. UMAP embeddings are entirely dependent on first ...
