A stochastic collocation method based on sparse grids for a stochastic Stokes-Darcy model

open access: yesDiscrete and Continuous Dynamical Systems - Series S, 2021
In this paper, we develop a sparse grid stochastic collocation method to improve the computational efficiency in handling the steady Stokes-Darcy model with random hydraulic conductivity.

The Seven-League Scheme: Deep Learning for Large Time Step Monte Carlo Simulations of Stochastic Differential Equations

open access: yesRisks, 2022
We propose an accurate data-driven numerical scheme to solve stochastic differential equations (SDEs), by taking large time steps. The SDE discretization is built up by means of the polynomial chaos expansion method, on the basis of accurately determined

An Adaptive WENO Collocation Method for Differential Equations with Random Coefficients

open access: yesMathematics, 2016
The stochastic collocation method for solving differential equations with random inputs has gained lots of popularity in many applications, since such a scheme exhibits exponential convergence with smooth solutions in the random space.

A multilevel stochastic collocation method for SPDEs [PDF]

open access: yesAIP Conference Proceedings, 2015
We present a multilevel stochastic collocation method that, as do multilevel Monte Carlo methods, uses a hierarchy of spatial approximations to reduce the overall computational complexity when solving partial differential equations with random inputs.
