A Generalised Linear Model Framework for $β$-Variational Autoencoders based on Exponential Dispersion Families

J. Mach. Learn. Res., 2020
Although variational autoencoders (VAE) are successfully used to obtain meaningful low-dimensional representations for high-dimensional data, the characterization of critical points of the loss function for general observation models is not fully understood.

Campatibility of solitons within the frame work of Estevez-Mansfield-Clarkson equation

Partial Differential Equations in Applied Mathematics
This work suggests single-wave solutions for the Estevez-Mansfield-Clarkson (EMC) and linked sine-Gordon equations. The shape generation process in droplet form is studied using these model equations.

Bernoulli Poisson Moment Exponential Distribution: Mathematical Properties, Regression Model, and Applications

International Journal of Mathematics and Mathematical Sciences
We introduce a new flexible count distribution by combining Bernoulli and Poisson moment exponential (PMEx) distributions. The new model named the Bernoulli PMEx distribution.

Towards a fully consistent Milky Way disc model: Part 1 The local model based on kinematic and photometric data

, 2009
We present a fully consistent evolutionary disc model of the solar cylinder. The model is based on a sequence of stellar sub-populations described by the star formation history (SFR) and the dynamical heating law (given by the age-velocity dispersion ...

Robust nonlinear regression: case study for modeling the greenhouse gases, methane and carbon dioxide concentration in atmosphere [PDF]

, 2014
Four nonlinear regression models are proposed for the atmospheric carbon dioxide and methane gas concentrations data, reported by United Nation 1989. Among those considered, the Exponential with Intercept is the most preferred one to model methane data ...

A Fractional - spread defuzzification framework for n-tuple fuzzy numbers with application to nonlinear optimization [PDF]

EPJ Web of Conferences
When decision variables exhibit asymmetric and multiscale uncertainty, ranking fuzzy numbers continues to be a major difficulty in nonlinear optimization.

NGC 6340: an old S0 galaxy with a young polar disc. Clues from morphology, internal kinematics and stellar populations

, 2009
Lenticular galaxies are believed to form by a combination of environmental effects and secular evolution. We study the nearby disc-dominated S0 galaxy NGC 6340 photometrically and spectroscopically to understand the mechanisms of S0 formation and ...

Asymptotic properties of the estimator for a finite mixture of exponential dispersion models

Filomat, 2018
This paper is concerned with a class of exponential dispersion distributions. We particularly focused on the mixture models, which represent an extension of the Gaussian distribution. It should be noted that the parameters estimation of mixture distributions is an important task in statistical processing. In order to estimate the parameters

Timing jitter in photon detection by straight superconducting nanowires: Effect of magnetic field and photon flux

, 2018
We studied the effect of the external magnetic field and photon flux on timing jitter in photon detection by straight superconducting NbN nanowires. At two wavelengths 800 and 1560 nm, statistical distribution in the appearance time of the photon count ...

Dynamics and stability of solitons in the higher-order dispersive cubic-quintic nonlinear schrödinger equation: conservation laws and applications

Discover Applied Sciences
This study investigates the construction of multi-peak solitons and various other wave solutions of a higher-order nonlinear Schrödinger equation incorporating cubic-quintic dispersion, using the modified exponential rational function method.
