Exponential Families with External Parameters [PDF]

open access: yesEntropy, 2022
In this paper we introduce a class of statistical models consisting of exponential families depending on additional parameters, called external parameters.

Revisiting Chernoff Information with Likelihood Ratio Exponential Families [PDF]

open access: yesEntropy, 2022
The Chernoff information between two probability measures is a statistical divergence measuring their deviation defined as their maximally skewed Bhattacharyya distance.

Statistical Divergences between Densities of Truncated Exponential Families with Nested Supports: Duo Bregman and Duo Jensen Divergences [PDF]

open access: yesEntropy, 2022
By calculating the Kullback–Leibler divergence between two probability measures belonging to different exponential families dominated by the same measure, we obtain a formula that generalizes the ordinary Fenchel–Young divergence.

On Representations of Divergence Measures and Related Quantities in Exponential Families [PDF]

open access: yesEntropy, 2021
Within exponential families, which may consist of multi-parameter and multivariate distributions, a variety of divergence measures, such as the Kullback–Leibler divergence, the Cressie–Read divergence, the Rényi divergence, and the Hellinger metric, can ...

Information Geometric Duality of ϕ-Deformed Exponential Families [PDF]

open access: yesEntropy, 2019
In the world of generalized entropies—which, for example, play a role in physical systems with sub- and super-exponential phase space growth per degree of freedom—there are two ways for implementing constraints in the maximum entropy ...

On the Limiting Behaviour of the Fundamental Geodesics of Information Geometry [PDF]

open access: yesEntropy, 2017
The Information Geometry of extended exponential families has received much recent attention in a variety of important applications, notably categorical data analysis, graphical modelling and, more specifically, log-linear modelling.

Generalised Exponential Families and Associated Entropy Functions

open access: yesEntropy, 2008
A generalised notion of exponential families is introduced. It is based on the variational principle, borrowed from statistical physics. It is shown that inequivalent generalised entropy functions lead to distinct generalised exponential families.

Deep Exponential Families [PDF]

open access: yes, 2014
We describe \textit{deep exponential families} (DEFs), a class of latent variable models that are inspired by the hidden structures used in deep neural networks.

Two Families of Continuous Probability Distributions Generated by the Discrete Lindley Distribution

open access: yesMathematics, 2023
In this paper, we construct two new families of distributions generated by the discrete Lindley distribution. Some mathematical properties of the new families are derived. Some special distributions from these families can be constructed by choosing some
