Spanners under the Hausdorff and Fréchet distances [PDF]

open access: greenInformation Processing Letters
We initiate the study of spanners under the Hausdorff and Fréchet distances. We show that any $t$-spanner of a planar point-set $S$ is a $\frac{\sqrt{t^2-1}}{2}$-Hausdorff-spanner and a $\min\{\frac{t}{2},\frac{\sqrt{t^2-t}}{\sqrt{2}}\}$-Fréchet spanner.

Document-Level Multi-Event Extraction with Event Proxy Nodes and Hausdorff Distance Minimization [PDF]

open access: yesAnnual Meeting of the Association for Computational Linguistics, 2023
Document-level multi-event extraction aims to extract the structural information from a given document automatically. Most recent approaches usually involve two steps: (1) modeling entity interactions; (2) decoding entity interactions into events ...

Hausdorff Measures on Generalized Set Valued Neutrosophic Quadruple Numbers and Decision Making Applications for Adequacy of Online Education [PDF]

open access: yesNeutrosophic Sets and Systems, 2021
In this paper, we develop a new method of decision-making algorithm with Hausdorff distance and Hausdorff similarity measures based on generalized set-valued neutrosophic quadruple numbers.

Determining the Hausdorff Distance Between Trees in Polynomial Time [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2021
The Hausdorff distance is a relatively new measure of similarity of graphs. The notion of the Hausdorff distance considers a special kind of a common subgraph of the compared graphs and depends on the structural properties outside of the common subgraph.

A hybrid Hausdorff distance track correlation algorithm based on time sliding window [PDF]

open access: yesMATEC Web of Conferences, 2021
In multi-sensor target tracking, track correlation is the key to the unification of global situation. Hausdorff distance has been applied to power fault elimination, point cloud data, medical measurement, image segmentation, vehicle trajectory ...

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.
