UMAP 0.6 optimizers lift attraction-repulsion restrictions, boost kNN recall
leland_mcinnes · x · 2026-11-11
UMAP was originally designed around a narrow slice of the attraction-repulsion spectrum; the 0.6 optimizers lift these restrictions, performing well at much higher repulsion strengths for better kNN recall. New optimizers/initialization are opt-in (set compatibilitylayout=False) and will become default in future versions.
