Multilevel and quasi-Monte Carlo methods for uncertainty quantification in particle travel times through random heterogeneous porous media [PDF]
In this study, we apply four Monte Carlo simulation methods, namely, Monte Carlo, quasi-Monte Carlo, multilevel Monte Carlo and multilevel quasi-Monte Carlo to the problem of uncertainty quantification in the estimation of the average travel time during ...

An efficient quasi-Monte Carlo method with forced fixed detection for photon scatter simulation in CT [PDF]
Detected scattered photons can cause cupping and streak artifacts, significantly degrading the quality of CT images. For fast and accurate estimation of scatter intensities resulting from photon interactions with a phantom, we first transform the path ...

Sequential Quasi Monte Carlo [PDF]
SummaryWe derive and study sequential quasi Monte Carlo (SQMC), a class of algorithms obtained by introducing QMC point sets in particle filtering. SQMC is related to, and may be seen as an extension of, the array-RQMC algorithm of L'Ecuyer and his colleagues. The complexity of SQMC is O{Nlog(N)}, where N is the number of simulations at each iteration,

A Quasi-Monte Carlo Method Based on Neural Autoregressive Flow [PDF]
This paper proposes a novel transport quasi-Monte Carlo framework that combines randomized quasi-Monte Carlo sampling with a neural autoregressive flow architecture for efficient sampling and integration over complex, high-dimensional distributions.

A quasi-Monte Carlo Metropolis algorithm [PDF]
This work presents a version of the Metropolis–Hastings algorithm using quasi-Monte Carlo inputs. We prove that the method yields consistent estimates in some problems with finite state spaces and completely uniformly distributed inputs. In some numerical examples, the proposed method is much more accurate than ordinary Metropolis–Hastings sampling.

Ionization cross sections for collisions between fully stripped ions and ground state hydrogen atoms using the quasi-classical trajectory Monte Carlo method [PDF]
We present ionization cross sections for collisions between fully stripped ions and ground state hydrogen atoms. In these calculations, we employ the standard three-body classical trajectory Monte Carlo (CTMC) and quasi-classical trajectory Monte Carlo ...

Population Quasi-Monte Carlo [PDF]
Monte Carlo methods are widely used for approximating complicated, multidimensional integrals for Bayesian inference. Population Monte Carlo (PMC) is an important class of Monte Carlo methods, which utilizes a population of proposals to generate weighted samples that approximate the target distribution.
