Quasi-Monte Carlo for SDE Simulation: Error Analysis and Dimensionality Reduction
Du Ouyang, Zexin Pan, Zhijian He
We investigate the numerical simulation of general stochastic differential equations (SDEs) using Quasi-Monte Carlo (QMC) methods. First, we provide a rigorous theoretical analysis…
Uncertainty quantification using importance-sampled quasi-Monte Carlo with dimension-independent convergence rates
Zexin Pan, Du Ouyang, Zhijian He
Quasi-Monte Carlo (QMC) integration over unbounded domains remains challenging due to the high dimensionality of sampling space and the boundary growth of the integr…
Quasi-Monte Carlo integration over with boundary-damping importance sampling
Zexin Pan, Du Ouyang, Zhijian He
This paper proposes a new importance sampling (IS) that is tailored to quasi-Monte Carlo (QMC) integration over . IS introduces a multiplicative adjustment to the int…
Generalization Error Analysis of Deep Backward Dynamic Programming for Solving Nonlinear PDEs
Du Ouyang, Jichang Xiao, Xiaoqun Wang
We explore the application of the quasi-Monte Carlo (QMC) method in deep backward dynamic programming (DBDP) (Hure et al. 2020) for numerically solving high-dimensional nonlinear p…
