DETERMINING THE VALUE OF DOUBLE BARRIER OPTION USING STANDARD MONTE CARLO, ANTITHETIC VARIATE, AND CONTROL VARIATE METHODS

open access: yesBarekeng, 2023
In this paper, we applied the standard Monte Carlo, antithetic variate, and control variates methods to value the double barrier knock-in option price.

Multifidelity Ensemble Kalman Filtering Using Surrogate Models Defined by Theory-Guided Autoencoders

open access: yesFrontiers in Applied Mathematics and Statistics, 2022
Data assimilation is a Bayesian inference process that obtains an enhanced understanding of a physical system of interest by fusing information from an inexact physics-based model, and from noisy sparse observations of reality. The multifidelity ensemble

Recursive Control Variates for Inverse Rendering

open access: yesACM Transactions on Graphics, 2023
We present a method for reducing errors---variance and bias---in physically based differentiable rendering (PBDR). Typical applications of PBDR repeatedly render a scene as part of an optimization loop involving gradient descent.

ANALISIS RISIKO PORTOFOLIO MENGGUNAKAN METODE SIMULASI MONTE CARLO CONTROL VARIATES

open access: yesE-Jurnal Matematika, 2021
Value at Risk (VaR) is a method to measure the maximum loss with a certain level of confidence in a certain period. Monte Carlo simulation is the most popular method of calculating VaR.

Adaptive Testing for Connected and Automated Vehicles with Sparse Control Variates in Overtaking Scenarios [PDF]

open access: yes2022 IEEE 25th International Conference on Intelligent Transportation Systems (ITSC), 2022
Testing and evaluation is a critical step in the development and deployment of connected and automated vehicles (CAVs). Due to the black-box property and various types of CAVs, how to test and evaluate CAVs adaptively remains a major challenge.

Multifidelity Reinforcement Learning with Control Variates [PDF]

open access: yesarXiv.org, 2022
In many computational science and engineering applications, the output of a system of interest corresponding to a given input can be queried at different levels of fidelity with different costs.

Control of Variation by Reward Probability. [PDF]

open access: yesJournal of Experimental Psychology: Animal Behavior Processes, 2004
Two bar-press experiments with rats tested the rule that reducing expectation of reward increases the variation from which reward selects. Experiment 1 used a discrete-trial random-interval schedule, with trials signaled by light or sound. One signal always ended with reward; the other signal ended with reward less often.

Bayesian control variates for optimal covariance estimation with pairs of simulations and surrogates [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2022
Predictions of the mean and covariance matrix of summary statistics are critical for confronting cosmological theories with observations, not least for likelihood approximations and parameter inference.

Control Variates for Quantile Estimation [PDF]

open access: yesManagement Science, 1987
New point and interval estimators for quantiles that employ a control variate are introduced. The properties of these estimators do not depend on the usual assumption of joint normality between the random variable of interest and the control. Illustrative examples for queueing and stochastic activity network models are given.
