UMAP scored higher than DiRe on local-neighborhood metrics at k = 16 in the arXiv experiment. UMAP partially tracked noise-induced beta1 inflation in the noisy figure-8 experiment. cuML UMAP had topology error 5 on all 11 OpenML datasets in the benchmark. The article cautions against treating UMAP islands and gaps as direct evidence of real scientific separations. UMAP’s local-neighborhood objective can conflict with global and topological structure.
