Answering Multi-Dimensional Analytical Queries under Local Differential Privacy
Summary: Answering multi-dimensional analytical (MDA) queries under local differential privacy (LDP). Proposes LDP encoders and estimation algorithms for predicates (categorical/ordinal) and aggregations, with tight error bounds and polylog dependence; scalable to high dimensions, validated on real/synthetic data against marginal-estimation baselines.
