Sentence examples for cheaper surrogate from inspiring English sources

Our aim in this paper is to build a cheaper surrogate of an individual-based (IB) model simulation of microbial communities.

Therefore a cheap surrogate model is used to capture the main trends of the objective and constraint functions.

In SBO, the direct optimization of the expensive model is replaced by iterative updating and re-optimization of its cheap surrogate model.

To cope with the cost of simulations, one replaces the real response surface with a cheap surrogate based, e.g., on polynomial chaos expansions, neural networks, support vector machines, or Gaussian processes (GP).

We focus on a specific optimization technique where, in order to reduce the design cost, the accurate high fidelity airfoil model is replaced by a cheap surrogate constructed from a low fidelity model and the shape preserving response prediction technique.

Surrogate modeling uses cheap "surrogates" to represent the response surface of simulation models.

The solution approaches that we present here rely on surrogate-based optimization (SBO) paradigm, where the design speedup is obtained by shifting the optimization burden into a cheap replacement model (the surrogate).

If a computer model is run many times with different inputs, the results obtained can often be used to derive a computationally cheaper approximation, or surrogate model, of the original computer code.

We present a mixed multifidelity importance sampling (MMFIS) approach that leverages computationally cheap but erroneous surrogate models for the construction of the biasing distribution and that uses the original high-fidelity model to guarantee unbiased estimates of the failure probability.

Sparse grid (SG) stochastic collocation methods have been recently used to build accurate but cheap-to-run surrogates for groundwater models to reduce the computational burden of Bayesian uncertainty analysis.

The wide availability and cheap cost of surrogates are two characteristics of these substances that should be tackled in interventions.
