Multidimensional persistent homology is stable [PDF]

open access: yes, 2009
Multidimensional persistence studies topological features of shapes by analyzing the lower level sets of vector-valued functions. The rank invariant completely determines the multidimensional analogue of persistent homology groups.

Object-oriented persistent homology [PDF]

open access: yesJournal of Computational Physics, 2016
Persistent homology provides a new approach for the topological simplification of big data via measuring the life time of intrinsic topological features in a filtration process and has found its success in scientific and engineering applications. However, such a success is essentially limited to qualitative data classification and analysis.

Formation of Machine Learning Features Based on the Construction of Tropical Functions

open access: yesМоделирование и анализ информационных систем, 2022
One of the main methods of computational topology and topological data analysis is persistent homology, which combines geometric and topological information about an object using persistent diagrams and barcodes.

Modeling of persistent homology [PDF]

open access: yesCommunications in Statistics - Theory and Methods, 2019
Topological Data Analysis (TDA) is a novel statistical technique, particularly powerful for the analysis of large and high dimensional data sets. Much of TDA is based on the tool of persistent homology, represented visually via persistence diagrams.

Probing Multipartite Entanglement Through Persistent Homology [PDF]

open access: yesCommunications in Mathematical Physics, 2023
We propose a study of multipartite entanglement through persistent homology, a tool used in topological data analysis. In persistent homology, a 1-parameter filtration of simplicial complexes called a persistence complex is used to reveal persistent ...

Filtered Feature Selection Algorithm Based on Persistent Homology [PDF]

open access: yesJisuanji kexue, 2023
The existing filtering feature selection algorithm ignores the correlation between features.This paper proposes a new filtering feature selection algorithm —the feature selection algorithm based on persistent homology(Rel-Betti algorithm),which can ...
