Intuitive explanation of how UMAP works, compared to t-SNE
The main difference between t-SNE and UMAP is the interpretation of the distance between objects or "clusters". I use the quotation marks since ...
PCA vs UMAP vs t-SNE: On a very layman level, what are ... - Reddit
They are similar applications (ie dimensionality reduction primarily for plotting), but that t-SNE does a better job at preserving local relationships.
The biggest difference between the the output of UMAP when compared with t-SNE is this balance between local and global structure - UMAP is often better at ...
Seeing data as t-SNE and UMAP do | Nature Methods
t-SNE and uniform manifold approximation and projection (UMAP) are among the tools life scientists turn to for dimension reduction.
Easy explanation of the dimension reduction (PCA, t-SNE, and UMAP)
PCA, t-SNE, and UMAP are techniques used to understand and visualize complex data. PCA captures global patterns, t-SNE emphasizes local patterns and clusters, ...
