structure, low density and chemical robustness. Despite the expanded efforts to understand …

The theory of multidimensional persistence

G Carlsson, A Zomorodian - Proceedings of the twenty-third annual …, 2007 - dl.acm.org
Persistent homology captures the topology of a filtration-a one-parameter family of
increasing spaces-in terms of a complete discrete invariant. This invariant is a multiset of …

Theory and algorithms for constructing discrete Morse complexes from grayscale digital images

V Robins, PJ Wood… - IEEE Transactions on …, 2011 - ieeexplore.ieee.org
We present an algorithm for determining the Morse complex of a two or three-dimensional
grayscale digital image. Each cell in the Morse complex corresponds to a topological …

Fast construction of the Vietoris-Rips complex

A Zomorodian - Computers & Graphics, 2010 - Elsevier
The Vietoris-Rips complex characterizes the topology of a point set. This complex is popular
in topological data analysis as its construction extends easily to higher dimensions. We …

[图书][B] Machine learning for health informatics

A Holzinger - 2016 - Springer
Abstract Machine Learning (ML) studies algorithms which can learn from data to gain

Computing multidimensional persistence

G Carlsson, G Singh, A Zomorodian - Algorithms and Computation: 20th …, 2009 - Springer
The theory of multidimensional persistence captures the topology of a multifiltration–a
multiparameter family of increasing spaces. Multifiltrations arise naturally in the topological …

Towards the augmented pathologist: Challenges of explainable-ai in digital pathology

A Holzinger, B Malle, P Kieseberg, PM Roth… - arXiv preprint arXiv …, 2017 - arxiv.org
Digital pathology is not only one of the most promising fields of diagnostic medicine, but at
the same time a hot topic for fundamental research. Digital pathology is not just the transfer …

Principal component analysis of persistent homology rank functions with case studies of spatial point patterns, sphere packing and colloids

V Robins, K Turner - Physica D: Nonlinear Phenomena, 2016 - Elsevier
Persistent homology, while ostensibly measuring changes in topology, captures multiscale
geometrical information. It is a natural tool for the analysis of point patterns. In this paper we …

Fisher forecasts for primordial non-Gaussianity from persistent homology

M Biagetti, J Calles, L Castiblanco… - Journal of Cosmology …, 2022 - iopscience.iop.org
We study the information content of summary statistics built from the multi-scale topology of
large-scale structures on primordial non-Gaussianity of the local and equilateral type. We …

Decreasing false-alarm rates in CNN-based solar flare prediction using SDO/HMI data

V Deshmukh, N Flyer, K Van der Sande… - The Astrophysical …, 2022 - iopscience.iop.org
A hybrid two-stage machine-learning architecture that addresses the problem of excessive
false positives (false alarms) in solar flare prediction systems is investigated. The first stage …
