Tail Conditional Moments for Location-Scale Mixture of Elliptical Distributions

Mathematics, 2022
We present the general results on the univariate tail conditional moments for a location-scale mixture of elliptical distributions. Examples include the location-scale mixture of normal, location-scale mixture of Student’s t, location-scale mixture of ...

A dynamic scale-mixture model of motion in natural scenes [PDF]

eLife
Some of the most important tasks of visual and motor systems involve estimating the motion of objects and tracking them over time. Such systems evolved to meet the behavioral needs of the organism in its natural environment and may therefore be adapted ...

On the Reversible Jump Markov Chain Monte Carlo (RJMCMC) Algorithm for Extreme Value Mixture Distribution as a Location-Scale Transformation of the Weibull Distribution

Applied Sciences, 2021
Data with a multimodal pattern can be analyzed using a mixture model. In a mixture model, the most important step is the determination of the number of mixture components, because finding the correct number of mixture components will reduce the error of ...

Scale Mixture of Gleser Distribution with an Application to Insurance Data

Mathematics
In this paper, the scale mixture of the Gleser (SMG) distribution is introduced. This new distribution is the product of a scale mixture between the Gleser (G) distribution and the Beta(a,1) distribution.

Quasi-Exponentiated Normal Distributions: Mixture Representations and Asymmetrization

Mathematics, 2023
In the paper, quasi-exponentiated normal distributions are introduced for any real power (exponent) no less than two. With natural exponents, the quasi-exponentiated normal distributions coincide with the distributions of the corresponding powers of ...

Analytic and Asymptotic Properties of the Generalized Student and Generalized Lomax Distributions

Mathematics, 2023
Analytic and asymptotic properties of the generalized Student and generalized Lomax distributions are discussed, with the main focus on the representation of these distributions as scale mixtures of the laws that appear as limit distributions in ...

AdamB: Decoupled Bayes by Backprop With Gaussian Scale Mixture Prior

IEEE Access, 2022
Overfitting of neural networks to training data is one of the most significant problems in machine learning. Bayesian neural networks (BNNs) are known to be robust against overfitting owing to their ability to model parameter uncertainty.
