On robust recovery of signals from indirect observations
Yannis Bekri, Anatoli Juditsky, Arkadi Nemirovski
We consider an uncertain linear inverse problem as follows. Given observation where and is observation noise, we want to re…
First order algorithms for computing linear and polyhedral estimates
Yannis Bekri, Anatoli Juditsky, Arkadi Nemirovski
It was recently shown [7, 9] that "properly built" linear and polyhedral estimates nearly attain minimax accuracy bounds in the problem of recovery of unknown signal from noisy obs…
On Robust Recovery of Signals from Indirect Observations
Yannis Bekri, Anatoli Juditsky, Arkadi Nemirovski
Our focus is on robust recovery algorithms in statistical linear inverse problem. We consider two recovery routines - the much studied linear estimate originating from Kuks and Olm…
Stochastic Mirror Descent for Large-Scale Sparse Recovery
Sasila Ilandarideva, Yannis Bekri, Anatoli Juditsky +1
In this paper we discuss an application of Stochastic Approximation to statistical estimation of high-dimensional sparse parameters. The proposed solution reduces to resolving a pe…
