No Fuss Distance Metric Learning Using Proxies [PDF]

open access: yesIEEE International Conference on Computer Vision, 2017
We address the problem of distance metric learning (DML), defined as learning a distance consistent with a notion of semantic similarity. Traditionally, for this problem supervision is expressed in the form of sets of points that follow an ordinal ...

Background Independent Quantum Mechanics, Metric of Quantum States, and Gravity: A Comprehensive Perspective

open access: yes, 2007
This paper presents a comprehensive perspective of the metric of quantum states with a focus on the background independent metric structures. We also explore the possibilities of geometrical formulations of quantum mechanics beyond the quantum state ...

A generalized metric space and related fixed point theorems

open access: yes, 2015
We introduce a new concept of generalized metric spaces for which we extend some well-known fixed point results including Banach contraction principle, Ćirić’s fixed point theorem, a fixed point result due to Ran and Reurings, and a fixed point result ...

Fixed Point Results for (ψ, ϕ)-Contractive Mapping in GF-Metric Space

open access: yesRatio Mathematica
The main goal of this work is to present GF -metric space, a new generalization of G-metric space. A comparison between the classes of G-metric spaces, GP-metric spaces, Gb-metric spaces, generalized Gb-metric spaces, and G∗ -metric spaces and the class ...

A metric space associated with probability space

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1993
For a complete probability space (Ω,∑,P), the set of all complete sub-σ-algebras of ∑, S(∑), is given a natural metric and studied. The questions of when S(∑) is compact or connected are awswered and the important subset consisting of all continuous sub ...

Extended rectangular fuzzy b-metric space with application

open access: yesAIMS Mathematics, 2022
In this paper, we introduce an extended rectangular fuzzy b-metric space which generalizes rectangular fuzzy b-metric space and rectangular fuzzy metric space. We show that an extended rectangular fuzzy b-metric space is not Hausdorff.

Fixed points of monotone nonexpansive mappings on a hyperbolic metric space with a graph

open access: yes, 2015
In this work, we define the concept of G-monotone nonexpansive multivalued mappings defined on a metric space with a graph G. Then we obtain sufficient conditions for the existence of fixed points for such mappings in hyperbolic metric spaces.

Test Spaces for Metric Spaces [PDF]

open access: yesProceedings of the American Mathematical Society, 1959
Introduction. Let n be a positive integer, and let yn be a topological space with the following property: a topological space X has dimension Yn can be extended over X. Then we call yn a test space for dimension n. In a previous paper [10], we characterized test spaces for dimension n under the assumption that both X and yn were separable metric.
