A Spatiotemporal Brain Network Analysis of Alzheimer’s Disease Based on Persistent Homology [PDF]

open access: yesFrontiers in Aging Neuroscience, 2022
Current brain network studies based on persistent homology mainly focus on the spatial evolution over multiple spatial scales, and there is little research on the evolution of a spatiotemporal brain network of Alzheimer’s disease (AD).

Fast computation of persistent homology representatives with involuted persistent homology

open access: yesFoundations of Data Science, 2023
Persistent homology is typically computed through persistent cohomology. While this generally improves the running time significantly, it does not facilitate extraction of homology representatives. The mentioned representatives are geometric manifestations of the corresponding holes and often carry desirable information.

A review of some properties of persistent homology

open access: yesDesimal, 2023
Every day, enormous complex geometric data are accumulating rapidly, and qualitative analysis is needed, which cannot be done properly without studying the shapes of those data.

On the Effectiveness of Persistent Homology

open access: yesAdvances in Neural Information Processing Systems 35, 2022
Persistent homology (PH) is one of the most popular methods in Topological Data Analysis. Even though PH has been used in many different types of applications, the reasons behind its success remain elusive; in particular, it is not known for which classes of problems it is most effective, or to what extent it can detect geometric or topological ...

Topology Applied to Machine Learning: From Global to Local

open access: yesFrontiers in Artificial Intelligence, 2021
Through the use of examples, we explain one way in which applied topology has evolved since the birth of persistent homology in the early 2000s. The first applications of topology to data emphasized the global shape of a dataset, such as the three-circle

Some Aspects of Persistent Homology Analysis on Phase Transition: Examples in an Effective QCD Model with Heavy Quarks

open access: yesUniverse, 2023
Recently, persistent homology analysis has been used to investigate phase structure. In this study, we apply persistent homology analysis to the QCD effective model with heavy quarks at finite imaginary chemical potential; i.e., the Potts model with the ...
