UMAP had consistently higher longest H0 bars and top-5-to-median ratios than DiRe. UMAP was described as 2 to 5 times more island-like than DiRe. UMAP visually fragmented continuous mathematical category relationships that DiRe represented with smoother inter-category continuity. Island-ness analysis used zero-dimensional persistence features from the two-dimensional arXiv layouts.
