Probabilistic Principal Geodesic Deep Metric Learning

open access: yesIEEE Access, 2022
Similarity learning which is useful for the purpose of comparing various characteristics of images in the computer vision field has been often applied for deep metric learning (DML).

The geometry of hemi-slant submanifolds of a locally product Riemannian manifold

open access: yesTURKISH JOURNAL OF MATHEMATICS, 2015
In the present paper, we study hemi-slant submanifolds of a locally product Riemannian manifold. We prove that the anti-invariant distribution which is involved in the definition of hemi-slant submanifold is integrable and give some applications of this result. We get a necessary and sufficient condition for a proper hemi-slant submanifold to be a hemi-

Local Hölder continuity of the isoperimetric profile in complete noncompact Riemannian manifolds with bounded geometry [PDF]

open access: yesGeometriae Dedicata, 2019
17 pages. This is an improvement of the result about the continuity of the isoperimetric profile function contained in arXiv:1404.3245. The arguments used here are a slight modification of the ones already used in arXiv:1404.3245.

Local scale symmetry in non-riemannian geometry based gravitational theories and the role of the noether current

open access: yesPhysical Review D, 2023
In this paper, we delve into the significance of local scale symmetry and the role of the associated noether current, within gravitational theories which are based in non-riemannian background space. Our focus is in Weyl and in Riemann-Cartan geometry based gravitational theories.

The jump and stagnation of mass with speed

open access: yesIET Quantum Communication, 2022
In the general theory of relativity, the four‐dimensional space‐time of describing a mass body accelerated motion or in a gravitational field, although it is a curved Riemannian geometric space from the perspective of “integral geometry”, but for any ...

Log‐Euclidean bag of words for human action recognition

open access: yesIET Computer Vision, 2015
Representing videos by densely extracted local space–time features has recently become a popular approach for analysing actions. In this study, the authors tackle the problem of categorising human actions by devising bag of words (BoWs) models based on ...

Swimming in Curved Surfaces and Gauss Curvature

open access: yesUniversitas Scientiarum, 2018
The Cartesian-Newtonian paradigm of mechanics establishes that, within an inertial frame, a body either remains at rest or moves uniformly on a line, unless a force acts externally upon it.
