Why topological data analysis detects financial bubbles? [PDF]

open access: yesCommunications in nonlinear science & numerical simulation, 2023
We present a heuristic argument for the propensity of Topological Data Analysis (TDA) to detect early warning signals of critical transitions in financial time series.

Analyzing Prospects for Quantum Advantage in Topological Data Analysis [PDF]

open access: yesPRX Quantum, 2022
Lloyd et al. were first to demonstrate the promise of quantum algorithms for computing Betti numbers, a way to characterize topological features of data sets.

Towards quantum advantage via topological data analysis [PDF]

open access: yesQuantum, 2022
Even after decades of quantum computing development, examples of generally useful quantum algorithms with exponential speedups over classical counterparts are scarce.

A Survey of Vectorization Methods in Topological Data Analysis [PDF]

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 2022
Attempts to incorporate topological information in supervised learning tasks have resulted in the creation of several techniques for vectorizing persistent homology barcodes. In this paper, we study thirteen such methods.

Simplicial complex entropy for time series analysis

open access: yesScientific Reports, 2023
The complex behavior of many systems in nature requires the application of robust methodologies capable of identifying changes in their dynamics. In the case of time series (which are sensed values of a system during a time interval), several methods ...

Complexity-Theoretic Limitations on Quantum Algorithms for Topological Data Analysis [PDF]

open access: yesPRX Quantum, 2022
Quantum algorithms for topological data analysis (TDA) seem to provide an exponential advantage over the best classical approach while remaining immune to dequantization procedures and the data-loading problem. In this paper, we give complexity-theoretic

Extending conventional surface roughness ISO parameters using topological data analysis for shot peened surfaces

open access: yesScientific Reports, 2022
The roughness of material surfaces is of greatest relevance for applications. These include wear, friction, fatigue, cytocompatibility, or corrosion resistance.

Topological Data Analysis

open access: yes, 2022
It has been observed since a long time that data are often carrying interesting topological and geometric structures. Characterizing such structures and providing efficient tools to infer and exploit them is a challenging problem that asks for new mathematics and that is motivated by a real need from applications.

Topological data analysis [PDF]

open access: yesNature Photonics, 2018
Topological data analysis (TDA) can broadly be described as a collection of data analysis methods that find structure in data. These methods include clustering, manifold estimation, nonlinear dimension reduction, mode estimation, ridge estimation and persistent homology. This paper reviews some of these methods.

A Primer on Topological Data Analysis to Support Image Analysis Tasks in Environmental Science [PDF]

open access: yesarXiv.org, 2022
Topological data analysis (TDA) is a tool from data science and mathematics that is beginning to make waves in environmental science. In this work, we seek to provide an intuitive and understandable introduction to a tool from TDA that is particularly ...
