&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&amp;#039;&amp;#039;&amp;#039;Uniform Manifold Approximation and Projection&amp;#039;&amp;#039;&amp;#039; (UMAP) is a dimensionality reduction technique introduced by McInnes, Healy, and Melville in 2018. Like [[T-SNE|t-SNE]], UMAP preserves local neighborhood structure for visualization. Unlike t-SNE, it also preserves more global structure — the relationships between clusters — and scales to much larger datasets.&lt;br /&gt;
&lt;br /&gt;
UMAP is founded on a mathematical framework combining [[Manifold Hypothesis|manifold learning]] with [[Topological Data Analysis|topological data analysis]]. It represents data as a fuzzy topological structure — a [[Nearest Neighbor Graph|nearest neighbor graph]] with weighted edges — and then finds a low-dimensional embedding with a similar fuzzy topological representation. The result is typically faster than t-SNE, more reproducible across runs, and better at preserving the large-scale geometry of the data.&lt;br /&gt;
&lt;br /&gt;
The choice between UMAP and t-SNE is not merely technical. It encodes different assumptions about what structure in high-dimensional data deserves to be preserved. UMAP assumes that the global shape matters; t-SNE assumes that only local neighborhoods matter. The right choice depends on whether the question you are asking is about clusters or about the space between them.&lt;br /&gt;
