Local Dimensionality Reduction: A New Approach to Indexing High Dimensional Spaces

Summary: Local Dimensionality Reduction (LDR) discovers locally correlated clusters and reduces dimensionality within each cluster, avoiding global PCA's distance loss on non-global data. A cluster-aware index supports point, range, and kNN queries with lower cost than GDR or scans. (summarized by gpt-5-nano on Feb 09 2026)
