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.

Deformed Algebras and Generalizations of Independence on Deformed Exponential Families [PDF]

open access: yesEntropy, 2015
A deformed exponential family is a generalization of exponential families. Since the useful classes of power law tailed distributions are described by the deformed exponential families, they are important objects in the theory of complex systems.

Conjugate Priors for Exponential Families

open access: yesAnnals of Statistics, 1979
Let $X$ be a random vector distributed according to an exponential family with natural parameter $\theta \in \Theta$. We characterize conjugate prior measures on $\Theta$ through the property of linear posterior expectation of the mean parameter of $X : E\{E(X|\theta)|X = x\} = ax + b$.

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 ...

Networked Exponential Families for Big Data Over Networks

open access: yesIEEE Access, 2020
The data generated in many application domains can be modeled as big data over networks, i.e., massive collections of high-dimensional local datasets related via an intrinsic network structure.

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 ...

Chentsov’s theorem for exponential families [PDF]

open access: yesInformation Geometry, 2017
Chentsov’s theorem characterizes the Fisher information metric on statistical models as the only Riemannian metric (up to rescaling) that is invariant under sufficient statistics.

Information Geometry of κ-Exponential Families: Dually-Flat, Hessian and Legendre Structures [PDF]

open access: yesEntropy, 2018
In this paper, we present a review of recent developments on the κ -deformed statistical mechanics in the framework of the information geometry.
