Journal ArticleDOI
Rapid airfoil design optimization via neural networks-based parameterization and surrogate modeling
TL;DR: In this article, a B-spline-based generative adversarial network (GAN) is used to filter out unrealistic airfoils for a reduced design space that contains all relevant airfoil shapes.
Journal ArticleDOI
Machine Learning in Aerodynamic Shape Optimization
TL;DR: In this article , the authors review the applications of ML in aerodynamic shape optimization (ASO) and provide a perspective on the state-of-the-art and future directions.
Journal ArticleDOI
Efficient yield estimation of multiband patch antennas by polynomial chaos‐based Kriging
Proceedings ArticleDOI
Application of Multifidelity Optimization Techniques to Benchmark Aerodynamic Design Problems
Jie Ren,Andrew S. Thelen,Anand Amrit,Xiaosong Du,Leifur T. Leifsson,Yonatan A. Tesfahunegn,Slawomir Koziel +6 more
TL;DR: Two-dimensional benchmark cases involving lift-constrained drag minimization in inviscid and viscous transonic flows are solved using derivative-free multi-fidelity optimization algorithms (space mapping and manifold mapping) and are compared with direct gradient-based optimization algorithms using adjoint sensitivities and trust regions.
Journal ArticleDOI
Optimum aerodynamic shape design under uncertainty by utility theory and metamodeling
Xiaosong Du,Leifur Leifsson +1 more
TL;DR: In this paper, a polynomial chaos expansion metamodel with the least-angle regression and the hyperbolic truncation scheme are used to accelerate the uncertainty propagation and the optimization process.
