Solution of linear ill-posed problems by model selection and aggregation
Felix Abramovich, Daniela De Canditiis, Marianna Pensky
We consider a general statistical linear inverse problem, where the solution is represented via a known (possibly overcomplete) dictionary that allows its sparse representation. We…
Spectral clustering in the dynamic stochastic block model
Marianna Pensky, Teng Zhang
In the present paper, we studied a Dynamic Stochastic Block Model (DSBM) under the assumptions that the connection probabilities, as functions of time, are smooth and that at most…
Anisotropic functional Laplace deconvolution
Rida Benhaddou, Marianna Pensky, Rasika Rajapakshage
In the present paper we consider the problem of estimating a three-dimensional function based on observations from its noisy Laplace convolution. Our study is motivated by the…
