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.

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 ...

Issues in the teaching and learning of geometry

open access: yes, 2002
This chapter analyses a range of key issues in the teaching and learning of geometry. These include the nature of geometry, why geometry is important in the curriculum at school level and beyond, what geometry can be included at the school level, the ...

Duality in Quantum Information Geometry [PDF]

open access: yesOpen Systems & Information Dynamics, 2004
Let [Formula: see text] be a separable Hilbert space. We consider the manifold [Formula: see text] consisting of density operators ρ on [Formula: see text] such that ρp is of trace class for some p ɛ (0, 1). We say [Formula: see text] is nearby ρ if there exists C > 1 such that C−1 ρ < σ < Cρ.

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.

Information Geometry of Dropout Training

open access: yesCoRR, 2022
Dropout is one of the most popular regularization techniques in neural network training. Because of its power and simplicity of idea, dropout has been analyzed extensively and many variants have been proposed. In this paper, several properties of dropout are discussed in a unified manner from the viewpoint of information geometry.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.
