WebFeb 21, 2024 · In this work, a data-driven surrogate model is proposed for the efficient prediction of blood flow simulations on similar but distinct domains. The proposed surrogate model leverages surface registration to parameterise those similar but distinct shapes and formulate corresponding hemodynamics information into geometry-informed snapshots … WebThe concept of surrogate modeling comprises a number of different approaches that depend on the type of the original model and the desired properties of the surrogate. In chemical process engineering, data-driven surrogate modeling is usually employed . This class of methods generally treats the original model as a black box with input–output ...

Surrogate Modelling: Data-driven Models for Machine Learning …
WebTo solve this problem, a data-driven sensitivity analysis method is proposed in this paper. The surrogate model of the original model is constructed by arbitrary Polynomial Chaos Expansion (aPCE), and different order sensitivity indices of the actual systems are calculated by Sobol’ combining with the Monte Carlo simulation. WebIn this paper, we develop such a surrogate model for divertor plasma detachment prediction with a data-driven approach. Unlike most data-driven surrogate models that directly connect two states $\boldsymbol {x}$ and $\boldsymbol {y}$, we take the indirect approach proposed by (Anirudh et al. 2024 ). WebFrequency-based Data-driven Surrogate Model for Efficient Prediction of Irregular Structure’s Seismic Responses. ... A frequency-based data-driven model was developed which predominantly uses the frequency spectrum of earthquakes as input data. The seismic responses of several structural components can be simultaneously generated as … merced county rules and regulations
