- Abstract:
- Distributed minimax estimation under communication constraints for Gaussian sequence model is examined. Basics in information theory are provided to motivate and present an algorithm using a uniquely decodable encoding function. The expected costs of the algorithm remain below the communication budget. An upper bound for a specific estimator and a lower bound are proven resulting in the minimax rate of convergence with respect to the mean squared error for distributed estimation over a given Besov class.
