Fisher Task Distance and its Application in Neural Architecture Search
IEEE Access, 2022 We formulate an asymmetric (or non-commutative) distance between tasks based on Fisher Information Matrices, called Fisher task distance. This distance represents the complexity of transferring the knowledge from one task to another.

Information entropies for the Morse potential using the J-matrix method
Results in Physics, 2017 Information entropies, such as Shannon, Fisher and Rényi entropies, with their associated quantities, are calculated and discussed for the Morse potential in the position (r) and momentum (p) spaces using the J-matrix method.

REDUCTION OF SAMPLE SIZE IN THE ANALYSIS OF SPATIAL VARIABILITY OF NONSTATIONARY SOIL CHEMICAL ATTRIBUTES [PDF]
Engenharia Agrícola, 2019 In the study of spatial variability of soil attributes, it is essential to define a sampling plan with adequate sample size. This study aimed to evaluate, through simulated data, the influence of parameters of the geostatistical model and sampling ...

Statistical Approach to Some Mathematical Problems
Austrian Journal of Statistics, 2016 A number of examples illustrate the following thesis. Mathematical problems involving the Fisher information have statistical roots. The list of examples includes (i) singularity of product measures with respect to their shifts, (ii) Carlen’s ...

From ƒ-Divergence to Quantum Quasi-Entropies and Their Use
Entropy, 2010 Csiszár’s ƒ-divergence of two probability distributions was extended to the quantum case by the author in 1985. In the quantum setting, positive semidefinite matrices are in the place of probability distributions and the quantum generalization is called ...

Clustering Financial Return Distributions Using the Fisher Information Metric
Entropy, 2019 Information geometry provides a correspondence between differential geometry and statistics through the Fisher information matrix. In particular, given two models from the same parametric family of distributions, one can define the distance between these

The Astrophysical Journal, 2023 It is well known that the power spectrum is not able to fully characterize the statistical properties of non-Gaussian density fields. Recently, many different statistics have been proposed to extract information from non-Gaussian cosmological fields that

Quantum Fisher information matrix and multiparameter estimation
Journal of Physics A: Mathematical and Theoretical, 2019 Abstract Quantum Fisher information matrix (QFIM) is a core concept in theoretical quantum metrology due to the significant importance of quantum Cramér–Rao bound in quantum parameter estimation. However, studies in recent years have revealed wide connections between QFIM and other aspects of quantum mechanics, including quantum ...
