Sentence examples for used variance reduction from inspiring English sources

In our GPU code, we used variance reduction techniques for photon transport as described for SIMIND and used a modified version of the analytical function for the geometrical response of the collimator, as first proposed by Metz et al. [29, 30] and extended to the simulated ARF as proposed by Song et al. [33].

We used 1,000 unpruned trees, and used variance reduction as a heuristic to select splits.

Since here we are predicting the cross-ethnic parameter, which is a continuous variable, the REPTree algorithm uses variance reduction to select the best node to split.

In this work, this MCNP calculation was repeated using variance reduction parameters generated by the Oak Ridge National Laboratory AutomateD VAriaNce reducTion Generator (ADVANTG) code and both MCNP calculations were compared in terms of computational efficiency and reliability.

Recent work has shown that it is possible to establish asymptotically valid confidence intervals for a quantile of the output of a model simulated using variance reduction techniques (VRTs).

With the growing interest in using the TRIPOLI-4® Monte Carlo radiation transport code for ITER applications, the aim of this paper is to study the feasibility to use variance reduction features of TRIPOLI-4 code on a 3D ITER benchmark model which is a 40° toroidal segment including 5796 vol cells.

The only way to reduce Monte Carlo error is to run more simulations or use variance reduction methods.

This situation arises when various physical processes, such as neutron transport, can generate additional particles during the time step, or when particle splitting is used for variance reduction.

Since this happens in a controlled manner the true distribution can be obtained afterward, as frequently used in variance reduction techniques.

The neutron response of the system was assessed using global variance reduction techniques and a surface source, and shutdown dose rate calculations were undertaken using MCR2S.

In this paper, we propose a Monte Carlo valuation algorithm that uses the variance reduction technique.
