Accuracy guaranties for $ℓ_{1}$ 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…

Sparse Non Gaussian Component Analysis by Semidefinite Programming

Elmar Diederichs, Anatoli Juditsky, Arkadi Nemirovski +1

Sparse non-Gaussian component analysis (SNGCA) is an unsupervised method of extracting a linear structure from a high dimensional data based on estimating a low-dimensional non-Gau…
