Arnak S. Dalalyan
We establish theoretical guarantees for the expected prediction error of the exponential weighting aggregate in the case of multivariate regression that is when the label vector is…

Restricted eigenvalue property for corrupted Gaussian designs
Philip Thompson, Arnak S. Dalalyan
Motivated by the construction of tractable robust estimators via convex relaxations, we present conditions on the sample size which guarantee an augmented notion of Restricted Eige…

Estimating linear functionals of a sparse family of Poisson means
Olivier Collier, Arnak Dalalyan
Assume that we observe a sample of size n composed of p-dimensional signals, each signal having independent entries drawn from a scaled Poisson distribution with an unknown intensi…
