umap for dimension reduction

[wangjiawen2013]

Linfa supports pca and tsne now. Uniform Manifold Approximation and Projection (UMAP) is a dimension reduction technique that can be used for visualisation similarly to t-SNE, but also for general non-linear dimension reduction (https://umap-learn.readthedocs.io/en/latest/). Since UMAP is becoming popular, does linfa support it ?

We're open to contributions implementing UMAP, but as far as I'm aware, it's not currently supported in Linfa and no one is currently working on implementing it.
