Sharp Variable Selection of a Sparse Submatrix in a High-Dimensional Noisy Matrix
Cristina Butucea, Yuri I. Ingster, Irina Suslina
We observe a matrix of independent, identically distributed Gaussian random variables which are centered except for elements of some submatrix of size where…

Minimax nonparametric testing in a problem related to the Radon transform
Yuri I. Ingster, Theofanis Sapatinas, Irina A. Suslina
We consider the detection problem of a two-dimensional function from noisy observations of its integrals over lines. We study both rate and sharp asymptotics for the error probabil…

Minimax signal detection in ill-posed inverse problems
Yuri I. Ingster, Theofanis Sapatinas, Irina A. Suslina
Ill-posed inverse problems arise in various scientific fields. We consider the signal detection problem for mildly, severely and extremely ill-posed inverse problems with -ell…
