Persistent homology classification algorithm [PDF]

open access: yesPeerJ Computer Science, 2023
Data classification is an important aspect of machine learning, as it is utilized to solve issues in a wide variety of contexts. There are numerous classifiers, but there is no single best-performing classifier for all types of data, as the no free lunch

Automatic epileptic seizure detection based on persistent homology [PDF]

open access: yesFrontiers in Physiology, 2023
Epilepsy is a prevalent brain disease, which is quite difficult-to-treat or cure. This study developed a novel automatic seizure detection method based on the persistent homology method.

Relational Persistent Homology for Multispecies Data with Application to the Tumor Microenvironment. [PDF]

open access: yesBull Math Biol, 2023
Topological data analysis (TDA) is an active field of mathematics for quantifying shape in complex data. Standard methods in TDA such as persistent homology (PH) are typically focused on the analysis of data consisting of a single entity (e.g., cells or ...

The persistent homology of genealogical networks [PDF]

open access: yesApplied Network Science, 2023
Genealogical networks (i.e. family trees) are of growing interest, with the largest known data sets now including well over one billion individuals. Interest in family history also supports an 8.5 billion dollar industry whose size is projected to double

The fiber of persistent homology for trees. [PDF]

open access: yesJ Appl Comput Topol, 2023
Consider the space of continuous functions on a geometric tree X whose persistent homology gives rise to a finite generic barcode D. We show that there are exactly as many path connected components in this space as there are merge trees whose barcode is ...

Leveraging Persistent Homology Features for Accurate Defect Formation Energy Predictions via Graph Neural Networks. [PDF]

open access: yesChem Mater
In machine-learning-assisted high-throughput defect studies, a defect-aware latent representation of the supercell structure is crucial for the accurate prediction of defect properties.

The persistent homology of mitochondrial ATP synthases [PDF]

open access: yesiScience, 2023
Summary: Relatively little is known about ATP synthase structure in protists, and the investigated ones exhibit divergent structures distinct from yeast or animals.

Persistent homology analysis distinguishes pathological bone microstructure in non-linear microscopy images. [PDF]

open access: yesSci Rep, 2023
We present a topological method for the detection and quantification of bone microstructure from non-linear microscopy images. Specifically, we analyse second harmonic generation (SHG) and two photon excited autofluorescence (TPaF) images of bone tissue ...
