The spatiotemporal MEG covariance matrix modeled as a sum of Kronecker products.

The single Kronecker product (KP) model for the spatiotemporal covariance of MEG residuals is extended to a sum of Kronecker products. This sum of KP is estimated such that it approximates the spatiotemporal sample covariance best in matrix norm. Contrary to the single KP, this extension allows for describing multiple, independent phenomena in the ongoing background activity. Whereas the single...

On Estimation of Covariance Matrices Modeled as a Sum of Kronecker Products

We address the problem of estimation of covariance matrices expressible as a sum of Kronecker products (KPs). Our goal is to arrive at estimates of the KP component matrices within a maximum-likelihood (ML) framework. Since the exact solution of the ML cost function is non-tractable, we propose a covariance-matching (CM) approach, noting that the estimates obtained from covariance-matching coin...

On a Kronecker products sum distance bounds

Abstract— binary linear error correcting codes represented by two code families Kronecker products sum are considered. The dimension and distance of new code is investigated. Upper and lower bounds of distance are obtained. Some examples are given. It is shown that some classic constructions are the private cases of considered one. The subclass of codes with equal lower and upper distance bound...

Modeling spatiotemporal noise covariance for MEG/EEG source analysis

We propose a new model for approximating spatiotemporal noise covariance for use in MEG/EEG source analysis. Our model is an extension of an existing model [1,2] that uses a single Kronecker product of a pair of matrices temporal and spatial covariance; we employ a series of Kronecker products in order to construct a better approximation of the full covariance. In contrast to the single-pair mo...
