A dynamical model of surrogate reactions [PDF]

open access: yesPhysical Review C, 2010
A new dynamical model is developed to describe the whole process of surrogate reactions; transfer of several nucleons at an initial stage, thermal equilibration of residues leading to washing out of shell effects and decay of populated compound nuclei ...

Efficient surrogate modeling methods for large-scale Earth system models based on machine-learning techniques [PDF]

open access: yesGeoscientific Model Development, 2019
Improving predictive understanding of Earth system variability and change requires data–model integration. Efficient data–model integration for complex models requires surrogate modeling to reduce model evaluation time. However, building a surrogate of a

Ensemble-Assisted Multi-Objective Optimization Algorithm Combining Feature Perturbation and Allocation Strategy [PDF]

open access: yesJisuanji gongcheng, 2022
A surrogate model can use its approximate prediction to replace the real evaluation of an algorithm when applied to the multi-objective optimization problem, which greatly reduces the number of real fitness evaluations required by the multi-objective ...

The Creation of Surrogate Models for Fast Estimation of Complex Model Outcomes. [PDF]

open access: yesPLoS ONE, 2016
A surrogate model is a black box model that reproduces the output of another more complex model at a single time point. This is to be distinguished from the method of surrogate data, used in time series.

Application of machine learning to develop a real-time air-cooled condenser monitoring platform using thermofluid simulation data

open access: yesEnergy and AI, 2021
A data-driven surrogate model is proposed for a 64-cell air-cooled condenser system at a power plant. The surrogate model was developed using thermofluid simulation data from an existing detailed 1-D thermofluid network simulation model.

Grid Enabled Surrogate Modeling [PDF]

open access: yes, 2009
The simulation and optimization of complex systems is a very time consuming and computationally intensive task. Therefore, global surrogate modeling methods are often used for the efficient exploration of the design space, as they reduce the number of simulations needed.

Evaluation of POD based surrogate models of fields resulting from nonlinear FEM simulations

open access: yesAdvanced Modeling and Simulation in Engineering Sciences, 2021
Surrogate modelling is a powerful tool to replace computationally expensive nonlinear numerical simulations, with fast representations thereof, for inverse analysis, model-based control or optimization.
