Point Cloud Denoising Algorithm via Geometric Metrics on the Statistical Manifold

open access: yesApplied Sciences, 2023
A denoising algorithm was proposed for point cloud with high-density noise. The algorithm utilized geometric metrics on the statistical manifold and applied the idea of clustering K-means based on local statistical characteristics between noise and valid

Foundations of Structural Statistics: Statistical Manifolds

open access: yesCoRR, 2020
Upon a consistent topological statistical theory the application of structural statistics requires a quantification of the proximity structure of model spaces. An important tool to study these structures are Pseudo-Riemannian metrices, which in the category of statistical models are induced by statistical divergences.

Conformal Control Tools for Statistical Manifolds and for γ-Manifolds

open access: yesMathematics, 2022
The theory of statistical manifolds w.r.t. a conformal structure is reviewed in a creative manner and developed. By analogy, the γ-manifolds are introduced. New conformal invariant tools are defined. A necessary condition for the f-conformal equivalence of γ-manifolds is found, extending that for the α-conformal equivalence for statistical manifolds ...

Statistical Manifolds with almost Quaternionic Structures and Quaternionic Kähler-like Statistical Submersions

open access: yesEntropy, 2015
In this paper we investigate statistical manifolds with almost quaternionic structures. We define the concept of quaternionic Kähler-like statistical manifold and derive the main properties of quaternionic Kähler-like statistical submersions, extending ...

Main Curvatures Identities on Lightlike Hypersurfaces of Statistical Manifolds and Their Characterizations

open access: yesMathematics, 2022
In this study, some identities involving the Riemannian curvature invariants are presented on lightlike hypersurfaces of a statistical manifold in the Lorentzian settings. Several inequalities characterizing lightlike hypersurfaces are obtained.

Characterizations of Transversal Lightlike Submanifolds in Indefinite Golden Statistical Geometry

open access: yesMathematics
We investigate transversal and radical transversal lightlike submanifolds (TLSs) of indefinite golden statistical manifolds (IGSMs). Using the dual affine connections associated with statistical structures, we obtain decomposition formulas and derive ...

F-Geometry and Amari’s α-Geometry on a Statistical Manifold

open access: yesEntropy, 2014
In this paper, we introduce a geometry called F-geometry on a statistical manifold S using an embedding F of S into the space RX of random variables. Amari’s α-geometry is a special case of F-geometry.

Statistical Solitons and Inequalities for Statistical Warped Product Submanifolds

open access: yesMathematics, 2019
Warped products play crucial roles in differential geometry, as well as in mathematical physics, especially in general relativity. In this article, first we define and study statistical solitons on Ricci-symmetric statistical warped products R ×

Hypersurfaces in statistical manifolds

open access: yesDifferential Geometry and its Applications, 2009
A statistical structure on a manifold \(M\) consists of a Riemannian metric \(g\) and a torsion-free affine connection \(\nabla\) that satisfies \( (\nabla_Xg)(Y,Z) = (\nabla_Yg)(X,Z)\) for all vector fields \(X\), \(Y\), and \(Z\) on \(M\). The statistical manifold \((M, \nabla, g)\) has constant curvature \(k\) if \[ R^\nabla(X,Y)Z = k(g(Y,Z)X-g(X,Z ...
