Embedding Quality Difference

[erenozcelik]

Hello @timsainb ,

When using Parametric UMAP for supervised tasks, the quality of the embeddings is significantly worse compared to the embeddings produced by standard UMAP. This difference is observed across multiple datasets and configurations. What could be the reason and can it be improved?

If you provide a specific issue and colab link reproducing it I can take a look. As it stands this issue is too vaguely described.

Hi,

Here is the colab link comparing parametric UMAP and standard UMAP for supervised FMNIST.
