UMAP_Dist

E Embedding

UMAP Distance Correlation

Direction

Higher is Better

Value Range

[-1, 1]

Category

Embedding

Neighborhood preservation in 2D views

Description

Spearman correlation between latent space and UMAP-reduced pairwise distance matrices

Mathematical Formula

ρ = spearmanr(D_latent.flatten(), D_umap.flatten())

Interpretation Guide

Measures global structure preservation in UMAP visualization. 1 = perfect distance rank preservation.
