Robust Kronecker Product PCA for Spatio-Temporal Covariance Estimation
Kristjan Greenewald, Alfred Hero
Kronecker PCA involves the use of a space vs. time Kronecker product decomposition to estimate spatio-temporal covariances. In this work the addition of a sparse correction factor…

Regularized Block Toeplitz Covariance Matrix Estimation via Kronecker Product Expansions
Kristjan Greenewald, Alfred O. Hero
In this work we consider the estimation of spatio-temporal covariance matrices in the low sample non-Gaussian regime. We impose covariance structure in the form of a sum of Kroneck…
