Computable Bounds for the Reach and r-Convexity of Subsets of

R Cotsakis - Discrete & Computational Geometry, 2024 - Springer
The convexity of a set can be generalized to the two weaker notions of positive reach and r-
convexity; both describe the regularity of a set's boundary. For any compact subset of R d …

Tight bounds for the learning of homotopy à la Niyogi, Smale, and Weinberger for subsets of Euclidean spaces and of Riemannian manifolds

D Attali, HDP Kouřimská, C Fillmore, I Ghosh, A Lieutier… - 2024 - hal.science
In this article we extend and strengthen the seminal work by Niyogi, Smale, and Weinberger
on the learning of the homotopy type from a sample of an underlying space. In their work …

On the notion of polynomial reach: A statistical application

A Cholaquidis, A Cuevas, L Moreno - Electronic Journal of …, 2024 - projecteuclid.org
The volume function V (t) of a compact set S∈ R d is just the Lebesgue measure of the set of
points within a distance to S not larger than t. According to some classical results in …

Statistical inference on unknown manifolds

C Berenfeld - 2022 - theses.hal.science
In high-dimensional statistics, the manifold hypothesis presumes that the data lie near low-
dimensional structures, called manifolds. This assumption helps explain why machine …

On standardness and the non-estimability of certain functionals of a set

A Cholaquidis, LM Beatriz - arXiv preprint arXiv:2306.16295, 2023 - arxiv.org
Standardness is a popular assumption in the literature on set estimation. It also appears in
statistical approaches to topological data analysis, where it is common to assume that the …

Optimal homotopy reconstruction results\a la Niyogi, Smale, and Weinberger

D Attali, HDP Kouřimská, C Fillmore, I Ghosh… - arXiv preprint arXiv …, 2022 - arxiv.org
In this article we show that the proof of the homotopy reconstruction result by Niyogi, Smale,
and Weinberger can be streamlined considerably using Federer's work on the reach and …

Computable bounds for the reach and -convexity of subsets of

R Cotsakis - arXiv preprint arXiv:2212.01013, 2022 - arxiv.org
The convexity of a set can be generalized to the two weaker notions of reach and $ r $-
convexity; both describe the regularity of a set's boundary. For any compact subset of …

Choosing the parameter of the Fermat distance: navigating geometry and noise

F Chazal, L Ferraris, P Groisman, M Jonckheere… - arXiv preprint arXiv …, 2023 - arxiv.org
The Fermat distance has been recently established as a useful tool for machine learning
tasks when a natural distance is not directly available to the practitioner or to improve the …

A Cholaquidis - Boletın de Estadıstica e Investigación Operativa BEIO, 2024 - seio.es
Some recent advances in Set Estimation, from 2009 to the present, are discussed. These
include some new findings, improved convergence rates, and new type of sets under study …
