UCIE maps to narrow LAB spectrum microbiome data about ucie

[savvas-paragkamian]

I tried with different dimension reduction methods like PCoA and nMDS and the U-CIE worked super.
I wonder though why this is the case for the UMAP data.
It is an error of my implementation of UMAP?
Or maybe has something to do with the nature of data?

Thank you so much for your nice words and the effort to make good use of it. I doubt that there was an error of your implementation of the UMAP algorithm. I tend to believe that UMAP's distribution is not centered, making the optimization algorithm not doing a a great job. I can have a look into it and if centering the data helps but feel free to do a PR if you have a nice implementation that works as well.

Happy to see that you got nice results! :D
