Federated Heavy Hitter Analytics with Local Differential Privacy
Summary: Introduces a target-aligning prefix-tree mechanism with epsilon-LDP for federated heavy hitter analytics. Adaptive extension balances prefix coverage with local heavy hitter estimation; consensus pruning uses cross-party priors to reveal hitters. (summarized by gpt-5-nano on Feb 09 2026)
