Ermakov Systems with Multiplicative Noise [PDF]

open access: yesPhysica A: Statistical Mechanics and its Applications, 2014
Using the Euler-Maruyama numerical method, we present calculations of the Ermakov-Lewis invariant and the dynamic, geometric, and total phases for several cases of stochastic parametric oscillators, including the simplest case of the stochastic harmonic ...

Power-law tails from multiplicative noise [PDF]

open access: yesPhysical Review Letters, 2004
We show that the well-known Langevin equation, modeling the Brownian motion and leading to a Gaussian stationary distribution of the corresponding Fokker-Planck equation, is changed by the smallest multiplicative noise.

Mapping multiplicative to additive noise [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2014
The Langevin formulation of a number of well-known stochastic processes involves multiplicative noise. In this work we present a systematic mapping of a process with multiplicative noise to a related process with additive noise, which may often be easier

SYNCHRONIZATION OF SYSTEMS WITH MULTIPLICATIVE NOISE [PDF]

open access: yesStochastics and Dynamics, 2008
The synchronization of Stratonovich stochastic differential equations (SDE) with a one-sided dissipative Lipschitz drift and linear multiplicative noise is investigated by transforming the SDE to random ordinary differential equations (RODE) and synchronizing their dynamics.

An Additive Approximation to Multiplicative Noise [PDF]

open access: yesJournal of Mathematical Imaging and Vision, 2020
Multiplicative noise models are often used instead of additive noise models in cases in which the noise variance depends on the state. Furthermore, when Poisson distributions with relatively small counts are approximated with normal distributions, multiplicative noise approximations are straightforward to implement. There are a number of limitations in

The impact of internal noise on the performance of convolutional neural network [PDF]

open access: yesИзвестия высших учебных заведений: Прикладная нелинейная динамика
Purpose. This study aims to establish the characteristics of noise propagation and accumulation in convolutional neural networks. The article investigates how the accuracy of a trained convolutional network varies depending on the type and intensity of ...

Time-scale analysis of abrupt changes corrupted by multiplicative noise [PDF]

open access: yes, 2000
Multiplicative Abrupt Changes (ACs) have been considered in many applications. These applications include image processing (speckle) and random communication models (fading).
