Indexing Multi-Dimensional Uncertain Data with Arbitrary Probability Density Functions

Summary: U-tree indexes multidimensional uncertain objects with arbitrary PDFs, supporting probabilistic rectangular range queries. A fully dynamic structure, it jointly optimizes I/O and CPU without imposing distributional assumptions. (summarized by gpt-5.6-luna on Jul 24 2026)
