Explicit mean-square error bounds
WebMar 1, 2024 · The error criteria we consider are the worst case root mean square error (the typical error criterion for randomized algorithms, sometimes referred to as “randomized error”, ) and the root mean square worst case error (sometimes referred to … WebMotivated, roughly, by comparing the mean and median of an IID sum of bounded lattice random variables, we develop explicit and e ective bounds on the errors in- volved in the one-term Edgeworth expansion for such sums.

WebDec 21, 2011 · Indeed, no model is able to achieve a Root Mean Square Error (RMSE) of less than 14 dB in rural environments and 8-9 dB in urban environments—a performance that is only achieved after substantial hand tuning. Explicit data-fitting approaches do not perform better, producing 8-9 dB RMSE as well.
