Probabilistic Autoencoder Using Fisher Information [PDF]
Entropy, 2021 Neural networks play a growing role in many scientific disciplines, including physics. Variational autoencoders (VAEs) are neural networks that are able to represent the essential information of a high dimensional data set in a low dimensional latent ...

Fisher Information Perspective of Pauli’s Electron [PDF]
Entropy, 2022 An electron moving at velocities much lower that the speed of light with a spin, is described by a wave function which is a solution of Pauli’s equation.

Dirac Equation and Fisher Information [PDF]
EntropyPreviously, it was shown that Schrödinger’s theory can be derived from a potential flow Lagrangian provided a Fisher information term is added. This approach was later expanded to Pauli’s theory of an electron with spin, which required a Clebsch flow ...

Decoherence, Anti-Decoherence, and Fisher Information [PDF]
Entropy, 2021 In this work, we study quantum decoherence as reflected by the dynamics of a system that accounts for the interaction between matter and a given field. The process is described by an important information geometry tool: Fisher’s information measure (FIM).

On a Conjecture regarding Fisher Information [PDF]
Advances in Mathematical Physics, 2015 Fisher’s information measure I plays a very important role in diverse areas of theoretical physics. The associated measures Ix and Ip, as functionals of quantum probability distributions defined in, respectively, coordinate and momentum spaces, are the ...

Discrete Versions of Jensen–Fisher, Fisher and Bayes–Fisher Information Measures of Finite Mixture Distributions [PDF]
Entropy, 2021 In this work, we first consider the discrete version of Fisher information measure and then propose Jensen–Fisher information, to develop some associated results.

Fisher Information of Free-Electron Landau States [PDF]
Entropy, 2021 An electron in a constant magnetic field has energy levels, known as the Landau levels. One can obtain the corresponding radial wavefunction of free-electron Landau states in cylindrical polar coordinates.

Transactional Interpretation for the Principle of Minimum Fisher Information [PDF]
Entropy, 2021 The principle of minimum Fisher information states that in the set of acceptable probability distributions characterizing the given system, it is best done by the one that minimizes the corresponding Fisher information.

Bayesian optimization of Fisher Information in nonlinear multiresonant quantum photonics gyroscopes [PDF]
NanophotonicsWe propose an on-chip gyroscope based on nonlinear multiresonant optics in a thin film χ (2) resonator that combines high sensitivity, compact form factor, and low power consumption simultaneously.

Characterizing (non-)Markovianity through Fisher information
SciPost Physics, 2023 A non-isolated physical system typically loses information to its environment, and when such loss is irreversible the evolution is said to be Markovian.
