Geometric Lower Bounds for Distributed Parameter Estimation Under Communication Constraints
IEEE Transactions on Information Theory(2021)
摘要
We consider parameter estimation in distributed networks, where each sensor in the network observes an independent sample from an underlying distribution and has $k$ bits to communicate its sample to a centralized processor which computes an estimate of a desired parameter. We develop lower bounds for the minimax risk of esti...
