2D UMAP projections of frozen encoder features, colored by biological label (and, for PathMNIST, by acquisition site).

Visualization only -- do not infer distance or separability from this view

UMAP and t-SNE are used here strictly for 2D visualization. This project never clusters on UMAP/t-SNE coordinates for its scientific claims (see analysis/dimensionality_reduction.py). A visually clean separation in this view does not imply strong clustering metrics in the original feature space, and a visually messy view does not imply the opposite -- see the results/dimensionality_reduction.parquet comparison on the Artifacts page for the quantitative version of this caution (hypothesis H4).
