Group invariant inferred distributions via noncommutative probability

open access: yes, 2006
One may consider three types of statistical inference: Bayesian, frequentist, and group invariance-based. The focus here is on the last method. We consider the Poisson and binomial distributions in detail to illustrate a group invariance method for ...

On the Continuity of Characteristic Functionals and Sparse Stochastic Modeling [PDF]

open access: yes, 2014
The characteristic functional is the infinite-dimensional generalization of the Fourier transform for measures on function spaces. It characterizes the statistical law of the associated stochastic process in the same way as a characteristic function ...

On the Moment Problem and Related Problems

open access: yesMathematics, 2021
Firstly, we recall the classical moment problem and some basic results related to it. By its formulation, this is an inverse problem: being given a sequence (yj)j∈ℕn  of real numbers and a closed subset F⊆ℝn, n∈{1,2,…}, find a positive regular Borel ...

Pseudodifferential operators associated with a semigroup of operators. [PDF]

open access: yes, 2014
20 pagesInternational audienceRelated to a semigroup of operators on a metric measure space, we define and study pseudodifferential operators (including the setting of Riemannian manifold, fractals, graphs ...).

Three-point functions in ${\cal N}=4$ SYM: the hexagon proposal at three loops [PDF]

open access: yes, 2015
Basso, Komatsu and Vieira recently proposed an all-loop framework for the computation of three-point functions of single-trace operators of ${\cal N}=4$ super-Yang-Mills, the "hexagon program".

Quantum deconvolution

open access: yes, 2017
We propose a method for stably removing noise from measurements of a quantum many-body system. The question is cast to a linear inverse problem by using a quantum Fischer information metric as figure of merit.

Readout of Majorana qubits

open access: yesPhysical Review Research, 2020
Schemes for topological quantum computation with Majorana bound states rely heavily on the ability to projectively measure products of Majorana operators. Here, we employ Markovian quantum measurement theory, including the readout device, to analyze such

Information preserving structures: A general framework for quantum zero-error information [PDF]

open access: yes, 2010
Quantum systems carry information. Quantum theory supports at least two distinct kinds of information (classical and quantum), and a variety of different ways to encode and preserve information in physical systems. A system's ability to carry information

The Waikato Region: Major tourism issues and opportunities to facilitate tourism development: Public summary [PDF]

open access: yes, 2007
A regional tourism project was commissioned by Katolyst, the Waikato Economic Development Agency, to assess the following: What is meant by regional tourism; the current views of industry stakeholders within the tourism and hospitality sectors; major ...

Evaluation of Focus Measures for Hyperspectral Imaging Microscopy Using Principal Component Analysis

open access: yesJournal of Imaging
An automatic focusing system is a crucial component of automated microscopes, adjusting the lens-to-object distance to find the optimal focus by maximizing the focus measure (FM) value.
