Image Restoration with Mean-Reverting Stochastic Differential Equations [PDF]

open access: yesInternational Conference on Machine Learning, 2023
This paper presents a stochastic differential equation (SDE) approach for general-purpose image restoration. The key construction consists in a mean-reverting SDE that transforms a high-quality image into a degraded counterpart as a mean state with fixed

Fuzzy stochastic differential equations driven by fractional Brownian motion

open access: yesAdvances in Differential Equations, 2021
In this paper, we consider fuzzy stochastic differential equations (FSDEs) driven by fractional Brownian motion (fBm). These equations can be applied in hybrid real-world systems, including randomness, fuzziness and long-range dependence.

Physics-Informed Generative Adversarial Networks for Stochastic Differential Equations [PDF]

open access: yesSIAM Journal on Scientific Computing, 2018
We developed a new class of physics-informed generative adversarial networks (PI-GANs) to solve in a unified manner forward, inverse and mixed stochastic problems based on a limited number of scattered measurements.

SPDIEs and BSDEs Driven by Lévy Processes and Countable Brownian Motions

open access: yesJournal of Function Spaces, 2016
The paper is devoted to solving a new class of backward stochastic differential equations driven by Lévy process and countable Brownian motions. We prove the existence and uniqueness of the solutions to the backward stochastic differential equations by ...

Studying Some Stochastic Differential Equations with trigonometric terms with Application

open access: yesZanco Journal of Pure and Applied Sciences, 2022
In this paper we look at several (trigonometric) stochastic differential equations, we find the general form for such nonlinear stochastic differential equation by using the I'to formula.

Approximation of solutions of multi-dimensional linear stochastic differential equations defined by weakly dependent random variables

open access: yesAIMS Mathematics, 2017
It is well-known that under suitable conditions there exists a unique solution of a ddimensional linear stochastic differential equation. The explicit expression of the solution, however, is not given in general.
