Population Quasi-Monte Carlo

چکیده

Monte Carlo methods are widely used for approximating complicated, multidimensional integrals Bayesian inference. Population (PMC) is an important class of methods, which adapts a population proposals to generate weighted samples that approximate the target distribution. When distribution expensive evaluate, PMC may encounter computational limitations since it requires many evaluations To address this, we propose new method, Quasi-Monte (PQMC), integrates ideas within sampling and adaptation steps PMC. A key novelty in PQMC idea importance support points resampling, deterministic method finding “optimal” subsample from proposal samples. Moreover, framework, develop efficient covariance strategy multivariate normal proposals. Finally, set correction weights introduced estimator improve efficiency standard estimator. We demonstrate improved empirical performance over extensive numerical simulations friction drilling application. Supplementary materials this article available online.

Monte Carlo Extension of Quasi-monte Carlo

This paper surveys recent research on using Monte Carlo techniques to improve quasi-Monte Carlo techniques. Randomized quasi-Monte Carlo methods provide a basis for error estimation. They have, in the special case of scrambled nets, also been observed to improve accuracy. Finally through Latin supercube sampling it is possible to use Monte Carlo methods to extend quasi-Monte Carlo methods to hi...

Monte Carlo and quasi-Monte Carlo methods

Monte Carlo is one of the most versatile and widely used numerical methods. Its convergence rate, O(N~^), is independent of dimension, which shows Monte Carlo to be very robust but also slow. This article presents an introduction to Monte Carlo methods for integration problems, including convergence theory, sampling methods and variance reduction techniques. Accelerated convergence for Monte Ca...

Error in Monte Carlo, quasi-error in Quasi-Monte Carlo

While the Quasi-Monte Carlo method of numerical integration achieves smaller integration error than standard Monte Carlo, its use in particle physics phenomenology has been hindered by the abscence of a reliable way to estimate that error. The standard Monte Carlo error estimator relies on the assumption that the points are generated independently of each other and, therefore, fails to account ...
