Variance reduction in MCMC [PDF]

open access: yes, 2003
We propose a general purpose variance reduction technique for MCMC estimators. The idea is obtained by combining standard variance reduction principles known for regular Monte Carlo simulations (Ripley, 1987) and the Zero-Variance principle introduced in

Choosing Transport Events for Initiating Splitting and Rouletting

open access: yesJournal of Nuclear Engineering, 2021
A study was performed to determine which transport events should be used to initiate a weight window lookup to achieve the best variance reduction performance.

TOWARDS ZERO-VARIANCE SCHEMES FOR KINETIC MONTE-CARLO SIMULATIONS [PDF]

open access: yesEPJ Web of Conferences, 2021
The solution of the time-dependent transport problem for neutrons and precursors in a nuclear reactor is hard to treat in a naive Monte-Carlo framework because of the largely different time scales associated to the prompt-fission chains and to the decay ...

ROBUST SIMULATION METHOD OF COMPLEX TECHNICAL TRANSPORT SYSTEMS [PDF]

open access: yesTransport Problems, 2021
In the optimization of technical systems focused on a specific functional purpose (reliability, safety, and availability) with the use of simulation methods, an important parameter is the digital simulation time of the research subject.

IMPLEMENTATION OF MONTE CARLO MOMENT MATCHING METHOD FOR PRICING LOOKBACK FLOATING STRIKE OPTION

open access: yesBarekeng, 2022
Monte Carlo method was a numerical method that was popular in finance. This method had disadvantages at convergences, so the moment matching was used to improve the efficiency from Monte Carlo method.

Pilot development: an empirical mixed-method analysis [PDF]

open access: yesJournal of Defense Analytics and Logistics, 2022
Purpose – Pilot upgrade training is critical to aircraft and passenger safety. This study aims to identify variances in the US Air Force C-130J pilot upgrade training based on geographic location and provide a model to enhance policy that will impact ...

Generalizing the Balance Heuristic Estimator in Multiple Importance Sampling

open access: yesEntropy, 2022
In this paper, we propose a novel and generic family of multiple importance sampling estimators. We first revisit the celebrated balance heuristic estimator, a widely used Monte Carlo technique for the approximation of intractable integrals.

INVESTIGATION ON DETERMINISTIC TRUNCATION TO CONTINUOUS ENERGY MONTE CARLO NEUTRON TRANSPORT CALCULATION [PDF]

open access: yesEPJ Web of Conferences, 2021
This paper presents the application and evaluation of a deterministic truncation of Monte Carlo (DTMC) solution method in a whole core reactor problem based on a continuous energy transport calculation. The DTMC method has been studied and developed as a

Bayesian autoregressive adaptive refined descriptive sampling algorithm in the Monte Carlo simulation

open access: yesStatistical Theory and Related Fields, 2023
This paper deals with the Monte Carlo Simulation in a Bayesian framework. It shows the importance of the use of Monte Carlo experiments through refined descriptive sampling within the autoregressive model $ X_{t}=\rho X_{t-1}+Y_{t} $ , where $ 0 \lt \rho

A Flexible Stochastic Multi-Agent ADMM Method for Large-Scale Distributed Optimization

open access: yesIEEE Access, 2022
While applying stochastic alternating direction method of multiplier (ADMM) methods has become enormously potential in distributed applications, improving the algorithmic flexibility can bring huge benefits.
