Description

I was aware that UMAP is using SGD, therefore, even we apply same parameters on same data, the 2D results are various. Is there any way to fix the 2D results for the same settings? It may be related to some previous question posts, please then redirect me to there. Appreciate it.

Research direction

Review UMAP's guidance on randomness and reproducibility, then check the previous question posts referenced in the issue. Confirm whether the same parameters and data can produce a repeatable 2D result, and document the relevant setting or redirect the reporter to an existing answer.
