Kählerian Information Geometry for Signal Processing

open access: yesEntropy, 2015
We prove the correspondence between the information geometry of a signal filter and a Kähler manifold. The information geometry of a minimum-phase linear system with a finite complex cepstrum norm is a Kähler manifold.

A Simple Approximation Method for the Fisher–Rao Distance between Multivariate Normal Distributions

open access: yesEntropy, 2023
We present a simple method to approximate the Fisher–Rao distance between multivariate normal distributions based on discretizing curves joining normal distributions and approximating the Fisher–Rao distances between successive nearby normal ...

Geometric Structures Induced by Deformations of the Legendre Transform

open access: yesEntropy, 2023
The recent link discovered between generalized Legendre transforms and non-dually flat statistical manifolds suggests a fundamental reason behind the ubiquity of Rényi’s divergence and entropy in a wide range of physical phenomena.

Non-Metricity in Information Geometry

open access: yesEntropy
The importance of non-metricity in information geometry is described through studies on gradient flow from the perspective of Weyl geometry. The Amari–Centsov tensor Ckij is the non-metricity tensor with respect to the α connection ∇(α) and Fisher metric

Far from Asymptopia: Unbiased High-Dimensional Inference Cannot Assume Unlimited Data

open access: yesEntropy, 2023
Inference from limited data requires a notion of measure on parameter space, which is most explicit in the Bayesian framework as a prior distribution. Jeffreys prior is the best-known uninformative choice, the invariant volume element from information ...

Geometry of Information Integration

open access: yes, 2017
Information geometry is used to quantify the amount of information integration within multiple terminals of a causal dynamical system. Integrated information quantifies how much information is lost when a system is split into parts and information ...

Change, time and information geometry

open access: yes, 2000
Dynamics, the study of change, is normally the subject of mechanics. Whether the chosen mechanics is ``fundamental'' and deterministic or ``phenomenological'' and stochastic, all changes are described relative to an external time.

F‐Manifolds and geometry of information [PDF]

open access: yesBulletin of the London Mathematical Society, 2020
The theory of $F$-manifolds, and more generally, manifolds endowed with commutative and associative multiplication of their tangent fields, was discovered and formalised in various models of quantum field theory involving algebraic and analytic geometry, at least since 1990's. The focus of this paper consists in the demonstration that various spaces of

Entropic Dynamics in a Theoretical Framework for Biosystems

open access: yesEntropy, 2023
Central to an understanding of the physical nature of biosystems is an apprehension of their ability to control entropy dynamics in their environment.

Lie groupoids in information geometry

open access: yes, 2019
We demonstrate that the proper general setting for contrast (potential) functions in statistical and information geometry is the one provided by Lie groupoids and Lie algebroids.
