Convex optimization for finite horizon robust covariance control of linear stochastic systems
Georgios Kotsalis, Guanghui Lan, Arkadi Nemirovski
This work addresses the finite-horizon robust covariance control problem for discrete-time, partially observable, linear system affected by random zero mean noise and deterministic…
Accuracy guaranties for recovery of block-sparse signals
Anatoli Juditsky, Fatma Kılınç Karzan, Arkadi Nemirovski +1
We introduce a general framework to handle structured models (sparse and block-sparse with possibly overlapping blocks). We discuss new methods for their recovery from incomplete o…
On Low Rank Matrix Approximations with Applications to Synthesis Problem in Compressed Sensing
Anatoli Juditsky, Fatma Kilinc Karzan, Arkadii S. Nemirovski
We consider the synthesis problem of Compressed Sensing - given s and an MXn matrix A, extract from it an mXn submatrix A', certified to be s-good, with m as small as possible. Sta…
On Verifiable Sufficient Conditions for Sparse Signal Recovery via Minimization
Anatoli Juditsky, Arkadii S. Nemirovski
We propose novel necessary and sufficient conditions for a sensing matrix to be "-good" - to allow for exact -recovery of sparse signals with nonzero entries when no…
