Nearly minimax robust estimator of the mean vector by iterative spectral dimension reduction
Amir-Hossein Bateni, Arshak Minasyan, Arnak S. Dalalyan
We study the problem of robust estimation of the mean vector of a sub-Gaussian distribution. We introduce an estimator based on spectral dimension reduction (SDR) and establish a f…

Confidence regions and minimax rates in outlier-robust estimation on the probability simplex
Amir-Hossein Bateni, Arnak S. Dalalyan
We consider the problem of estimating the mean of a distribution supported by the -dimensional probability simplex in the setting where an fraction of observations…
