On the Hausdorff and packing measures of typical compact metric spaces

open access: yesAequationes Mathematicae, 2018
We study the Hausdorff and packing measures of typical compact metric spaces belonging to the Gromov–Hausdorff space (of all compact metric spaces) equipped with the Gromov–Hausdorff metric.

On (semi)topology L-algebras [PDF]

open access: yesCategories and General Algebraic Structures with Applications, 2023
Here, we define (semi)topological L-algebras and some related results are approved. Then we deduce conditions that mention an L-algebra to be a semi-topological or a topological L-algebra and we check some attributes of them.

Hausdorff compactifications [PDF]

open access: yesTopology and its Applications, 2021
Previously, the authors used the insights of Robinson's non-standard analysis as a powerful tool to extend and simplify the construction of some compactifications of regular spaces. They now show that any Hausdorff compactification is obtainable with their method.

The Gromov–Hausdorff distance between spheres [PDF]

open access: yesGeometry & Topology, 2021
We provide general upper and lower bounds for the Gromov-Hausdorff distance $d_{\mathrm{GH}}(\mathbb{S}^m,\mathbb{S}^n)$ between spheres $\mathbb{S}^m$ and $\mathbb{S}^n$ (endowed with the round metric) for $0\leq ...

The 100th anniversary of fractal geometry: From Julia and Fatou through Hausdorff and Besicovitch to Mandelbrot [PDF]

open access: yesИзвестия высших учебных заведений: Прикладная нелинейная динамика, 2020
The purpose of this article is to present the biographies of the main creators of fractal geometry from the moment the first ideas arose, when the term «fractal» did not exist, to the present day.

A Generalized Hausdorff Distance Based Quality Metric for Point Cloud Geometry [PDF]

open access: yesInternational Workshop on Quality of Multimedia Experience, 2020
Reliable quality assessment of decoded point cloud geometry is essential to evaluate the compression performance of emerging point cloud coding solutions and guarantee some target quality of experience.

On the usage of average Hausdorff distance for segmentation performance assessment: hidden error when used for ranking

open access: yesEuropean Radiology Experimental, 2021
Average Hausdorff distance is a widely used performance measure to calculate the distance between two point sets. In medical image segmentation, it is used to compare ground truth images with segmentations allowing their ranking.

Hausdorff dimension, heavy tails, and generalization in neural networks [PDF]

open access: yesNeural Information Processing Systems, 2020
Despite its success in a wide range of applications, characterizing the generalization properties of stochastic gradient descent (SGD) in non-convex deep learning problems is still an important challenge.
