The persistence landscape and some of its properties

open access: yes, 2019
Persistence landscapes map persistence diagrams into a function space, which may often be taken to be a Banach space or even a Hilbert space. In the latter case, it is a feature map and there is an associated kernel. The main advantage of this summary is

A Geometric View on Constrained M-Estimators [PDF]

open access: yes, 2015
We study the estimation error of constrained M-estimators, and derive explicit upper bounds on the expected estimation error determined by the Gaussian width of the constraint set.

Rank penalized estimation of a quantum system

open access: yes, 2013
We introduce a new method to reconstruct the density matrix $\rho$ of a system of $n$-qubits and estimate its rank $d$ from data obtained by quantum state tomography measurements repeated $m$ times.

Distance statistics in random media: high dimension and/or high neighborhood order cases

open access: yes, 2014
Consider an unlimited homogeneous medium disturbed by points generated via Poisson process. The neighborhood of a point plays an important role in spatial statistics problems. Here, we obtain analytically the distance statistics to $k$th nearest neighbor

Generalized Measure of Entropy, Mathai's Distributional Pathway Model, and Tsallis Statistics

open access: yes, 2006
The pathway model of Mathai (2005) mainly deals with the rectangular matrix-variate case. In this paper the scalar version is shown to be associated with a large number of probability models used in physics.

Statistical topological data analysis using persistence landscapes [PDF]

open access: yes, 2015
We define a new topological summary for data that we call the persistence landscape. Since this summary lies in a vector space, it is easy to combine with tools from statistics and machine learning, in contrast to the standard topological summaries ...

Random perturbation of low rank matrices: Improving classical bounds

open access: yes, 2017
Matrix perturbation inequalities, such as Weyl's theorem (concerning the singular values) and the Davis-Kahan theorem (concerning the singular vectors), play essential roles in quantitative science; in particular, these bounds have found application in ...
