On Asymptotic Linear Convergence Rate of Iterative Hard Thresholding for Matrix Completion
Trung Vu, Evgenia Chunikhina, Raviv Raich
Iterative hard thresholding (IHT) has gained in popularity over the past decades in large-scale optimization. However, convergence properties of this method have only been explored…
Perturbation expansions and error bounds for the truncated singular value decomposition
Trung Vu, Evgenia Chunikhina, Raviv Raich
Truncated singular value decomposition is a reduced version of the singular value decomposition in which only a few largest singular values are retained. This paper presents a nove…
The C-SHIFT algorithm for normalizing covariances
Evgenia Chunikhina, Paul Logan, Yevgeniy Kovchegov +3
Omics technologies are powerful tools for analyzing patterns in gene expression data for thousands of genes. Due to a number of systematic variations in experiments, the raw gene e…
Entropy rates for Horton self-similar trees
Evgenia V. Chunikhina
In this paper we examine planted binary plane trees. First, we provide an exact formula for the number of planted binary trees with given Horton-Strahler orders. Then, using the no…
Confidence-constrained joint sparsity recovery under the Poisson noise model
E. Chunikhina, R. Raich, T. Nguyen
Our work is focused on the joint sparsity recovery problem where the common sparsity pattern is corrupted by Poisson noise. We formulate the confidence-constrained optimization pro…
