Information-Geometric Approach for a One-Sided Truncated Exponential Family [PDF]

open access: yesEntropy, 2023
In information geometry, there has been extensive research on the deep connections between differential geometric structures, such as the Fisher metric and the α-connection, and the statistical theory for statistical models satisfying regularity ...

Exponential Families with External Parameters

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.

The q-exponential family in statistical physics

open access: yesOpen Physics, 2009
The notion of generalised exponential family is considered in the restricted context of nonextensive statistical physics. Examples are given of models belonging to this family.

Sparse Exponential Family Principal Component Analysis. [PDF]

open access: yesPattern Recognit, 2016
We propose a Sparse exponential family Principal Component Analysis (SePCA) method suitable for any type of data following exponential family distributions, to achieve simultaneous dimension reduction and variable selection for better interpretation of the results. Because of the generality of exponential family distributions, the method can be applied

Registration for exponential family functional data. [PDF]

open access: yesBiometrics, 2019
Summary We introduce a novel method for separating amplitude and phase variability in exponential family functional data. Our method alternates between two steps: the first uses generalized functional principal components analysis to calculate template functions, and the second estimates smooth warping functions that map observed curves ...

Extended Divergence on a Foliation by Deformed Probability Simplexes

open access: yesEntropy, 2022
This study considers a new decomposition of an extended divergence on a foliation by deformed probability simplexes from the information geometry perspective.

On a Variational Definition for the Jensen-Shannon Symmetrization of Distances Based on the Information Radius

open access: yesEntropy, 2021
We generalize the Jensen-Shannon divergence and the Jensen-Shannon diversity index by considering a variational definition with respect to a generic mean, thereby extending the notion of Sibson’s information radius.

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

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

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 ...

Entropic Dynamics on Gibbs Statistical Manifolds

open access: yesEntropy, 2021
Entropic dynamics is a framework in which the laws of dynamics are derived as an application of entropic methods of inference. Its successes include the derivation of quantum mechanics and quantum field theory from probabilistic principles.
