Visualization of the final classification results using UMAP. The UMAP dimensionality reduction technique projects the five classified galaxy types into a two-dimensional space. Panel (a) shows the dimensionality reduction results for a random subset of 500 samples, panel (b) for 2000 samples, and panel (c) for the entire dataset. The contours in panel (d) enclose 20%, 50%, and 80% of the corresponding samples.
