PyTorch domain … Web12 Apr 2024 · UMAP claims to preserve both local and most of the global structure in the data. This means with t-SNE you cannot interpret the distance between clusters A and B at different ends of your plot. You cannot infer that these clusters are more dissimilar than A and C, where C is closer to A in the plot.
