PriPL-Tree: Accurate Range Query for Arbitrary Distribution under Local Differential Privacy

Summary: PriPL-Tree: hierarchical LDP structure that models node distributions with piecewise-linear fits instead of the usual uniform-within-partition assumption, improving range-query accuracy with few segments. Multidimensional extension uses data-aware adaptive grids built from PriPL marginals. (summarized by gpt-5-mini on Feb 09 2026)
