A Taiwanese individual compiled a detailed map of PLA military bases in China, originally on Google Maps, now transferred to uMap with descriptions of bases and equipment.
This thread describes how to plot thousands of Obsidian notes into a 3D semantic embedding space using model2vec and UMAP to reveal hidden patterns and blind spots in one's thinking.
ScaleMAP is a new nonlinear dimensionality reduction method that preserves local density and neighborhood structure by rescaling embedding distances based on original-space local radii, achieving better density preservation than DensMAP while maintaining UMAP-level neighborhood preservation.
