Gaussian approximation of Gaussian scale mixture [PDF]

open access: yesKybernetika, 2019
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.

Multiplying a Gaussian Matrix by a Gaussian Vector [PDF]

open access: yesStatistics & Probability Letters, 2017
We provide a new and simple characterization of the multivariate generalized Laplace distribution. In particular, this result implies that the product of a Gaussian matrix with independent and identically distributed columns by an independent isotropic ...

A Family of non-Gaussian Martingales with Gaussian Marginals [PDF]

open access: yesJournal of Applied Mathematics and Stochastic Analysis, 2006
We construct a family of non-Gaussian martingales the marginals of which are all Gaussian. We give the predictable quadratic variation of these processes and show they do not have continuous paths. These processes are Markovian and inhomogeneous in time,

Eigenvalues and eigenvectors for a hermitian gaussian operator: Role of the Schrödinger-Robertson uncertainty relation

open access: yesElectronic Research Archive, 2023
The eigenvalues and eigenvectors of a normalized gaussian operator do not seem to have been previously considered. I solve this problem for 1-dimensional translational systems.

Gaussian-Based Visualization of Gaussian and Non-Gaussian-Based Clustering [PDF]

open access: yesJournal of Classification, 2020
A generic method is introduced to visualize in a “Gaussian-like way,” and onto $\mathbb {R}^{2}$ , results of Gaussian or non-Gaussian–based clustering. The key point is to explicitly force a visualization based on a spherical Gaussian mixture to inherit ...

Gaussian Processes and Gaussian Measures [PDF]

open access: yesThe Annals of Mathematical Statistics, 1972
The subject of this paper is the study of the correspondence between Gaussian processes with paths in linear function spaces and Gaussian measures on function spaces. For the function spaces $C(I), C^n\lbrack a, b\rbrack, AC\lbrack a, b\rbrack$ and $L_2(T, \mathscr{A}, \nu)$ it is shown that if a Gaussian process has paths in these spaces then it ...

Modeling with generalized linear model on covid-19: Cases in Indonesia

open access: yesInternational Journal of Electronics and Communications System, 2021
The ongoing Covid-19 outbreak has made scientists continue to research this Covid-19 case. Most of the research carried out is on the prediction and modeling of Covid-19 data. This study will also discuss Covid-19 data modeling.

A compact weak measurement to observe the spin Hall effect of light

open access: yesNanophotonics, 2023
The spin Hall effect of light (SHEL), a microscopic and transverse splitting of linearly polarized light into circularly polarized components during refraction and reflection, can be measured at subnanometer scales using weak measurements and has emerged

A Robust Framework for Epidemic Analysis, Prediction and Detection of COVID-19

open access: yesFrontiers in Public Health, 2022
Covid-19 has become a pandemic that affects lots of individuals daily, worldwide, and, particularly, the widespread disruption in numerous countries, namely, the US, Italy, India, Saudi Arabia. The timely detection of this infectious disease is mandatory

The Generalization of Gaussians and Leonardo’s Octonions

open access: yesAnnales Mathematicae Silesianae, 2023
In order to explore the Leonardo sequence, the process of complex-ification of this sequence is carried out in this work. With this, the Gaussian and octonion numbers of the Leonardo sequence are presented.
