Local Differentially Private Heavy Hitter Detection in Data Streams with Bounded Memory

Summary: HG-LDP jointly optimizes local differential privacy, bounded memory, and Top-k accuracy for streaming heavy hitters. It introduces three LDP randomization schemes for large domains under bounded memory, achieving 2300x memory savings at 41,270 and favorable privacy/accuracy tradeoffs; code released.
