Feature Request: Accept custom distance function based on labels

[krrishh-org]

I have a distance matrix precalculated for each pair of labels, and I would like to pass that distance instead of eucliden or some other method.

It will e helpful if the distanceFn accepts a function that takes two labels as arguments and return the distance.

You can already do this. See this example: https://observablehq.com/@fil/umap-simple-topologies

Hi @zdk123,

Thank you for this. But I needed the distanceFn to be invoked using the labels instead of indices for supervised projection. I created a workaround in my local by mapping labels to indices.
