Simple proof of the risk bound for denoising by exponential weights for asymmetric noise distributions
Arnak S. Dalalyan
In this note, we consider the problem of aggregation of estimators in order to denoise a signal. The main contribution is a short proof of the fact that the exponentially weighted…

Matching Map Recovery with an Unknown Number of Outliers
Arshak Minasyan, Tigran Galstyan, Sona Hunanyan +1
We consider the problem of finding the matching map between two sets of -dimensional noisy feature-vectors. The distinctive feature of our setting is that we do not assume that…

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…
