Researchers have developed a new adaptive mean estimator designed for scenarios with 1-bit communication constraints. This estimator is proven to be $(\epsilon, \delta)$-PAC for distributions with bounded means and moments, achieving order-optimal sample complexity across various tail regimes. The work also highlights a significant adaptivity gap, showing that non-adaptive estimators are vastly less sample efficient. AI
