Convergence of persistence diagrams for discrete time stationary processes

Andrew M. Thomas

In this article we establish two fundamental results for the sublevel set persistent homology for stationary processes indexed by the positive integers. The first is a strong law o…

Dynamic Atomic Column Detection in Transmission Electron Microscopy Videos via Ridge Estimation

Yuchen Xu, Andrew M. Thomas, Peter A. Crozier +1

Ridge detection is a classical tool to extract curvilinear features in image processing. As such, it has great promise in applications to material science problems; specifically, f…

Fractal dimension, approximation and data sets

L. Betti, I. Chio, J. Fleischman +13

The purpose of this paper is to study the fractal phenomena in large data sets and the associated questions of dimension reduction. We examine situations where the classical Princi…

Feature detection and hypothesis testing for extremely noisy nanoparticle images using topological data analysis

Andrew M. Thomas, Peter A. Crozier, Yuchen Xu +1

We propose a flexible algorithm for feature detection and hypothesis testing in images with ultra low signal-to-noise ratio using cubical persistent homology. Our main application…

The VC-dimension of a class of multiples of the primes, and a connection to AdaBoost

Andrew M. Thomas

We discuss the VC-dimension of a class of multiples of integers and primes (equivalently indicator functions) and demonstrate connections to prime counting functions. Additionally,…

Central limit theorems and asymptotic independence for local -statistics on diverging halfspaces

Andrew M. Thomas

We consider the stochastic behavior of a class of local -statistics of Poisson processeswhich include subgraph and simplex counts as special cases, and amounts to quantifying…
