Gaussian approximation of Gaussian scale mixtures [PDF]

Kybernetika, 2021
For a given positive random variable $V>0$ and a given $Z\sim N(0,1)$ independent of $V$, we compute the scalar $t_0$ such that the distance between $Z\sqrt{V}$ and $Z\sqrt{t_0}$ in the $L^2(\R)$ sense, is minimal. We also consider the same problem in several dimensions when $V$ is a random positive definite matrix.

Indirect Gaussian Graph Learning Beyond Gaussianity [PDF]

IEEE Transactions on Network Science and Engineering, 2020
This paper studies how to capture dependency graph structures from real data which may not be Gaussian. Starting from marginal loss functions not necessarily derived from probability distributions, we utilize an additive over-parametrization with shrinkage to incorporate variable dependencies into the criterion.

Gaussian Integers [PDF]

Formalized Mathematics, 2013
Summary Gaussian integer is one of basic algebraic integers. In this article we formalize some definitions about Gaussian integers [27]. We also formalize ring (called Gaussian integer ring), Z-module and Z-algebra generated by Gaussian integer mentioned above.

Gaussianizing the non-Gaussian lensing convergence field: The performance of the Gaussianization [PDF]

Physical Review D, 2011
Motivated by recent works of Neyrinck et al. 2009 and Scherrer et al. 2010, we proposed a Gaussianization transform to Gaussianize the non-Gaussian lensing convergence field $κ$. It performs a local monotonic transformation $κ\rightarrow y$ pixel by pixel to make the unsmoothed one-point probability distribution function of the new variable $y ...

2D affine transform parameters by Gaussian elimination with pivoting [PDF]

Archives of Civil Engineering
In many geomatics, computer vision, and computer-aided applications, coordinate transformations are needed to transform from one coordinate system to another, especially in geodesy and photogrammetry.

Are the program packages for molecular structure calculations really black boxes? [PDF]

Journal of the Serbian Chemical Society, 2007
In this communication it is shown that the widely held opinion that compact program packages for quantum-mechanical calculations of molecular structure can safely be used as black boxes is completely wrong.

Gaussian process model based predictive control [PDF]

, 2003
Gaussian process models provide a probabilistic non-parametric modelling approach for black-box identification of non-linear dynamic systems. The Gaussian processes can highlight areas of the input space where prediction quality is poor, due to the lack ...
