If you accept t sne or umap as being useful because it unveils some structure and pacmap has mathematical guarantees to preserve the same or more structure, is that not enough as a motivation?

Fwiw, I use pacmap when building pipelines to get a feel whether a model is capturing signals as expected, for which it works better than the two due to the structure preserving making the conceptual mapping easier

I agree with you that it is correct from a logical perspective; I’m talking more about a narrative perspective. Any paper benefits from having at least one or two non-toy/bon-benchmark problems IMO.

What mathematical guarantees? I don't see any mathematical results in the paper.
