“…A variant is the quasi-random sampling using low-discrepancy sequences [55,59], such as Halton or Sobol sequence, which tends to provide more equidistributed samples in the parameter space. For different probability distributions of the parameter, weighted reduced basis/POD methods [26,62,64] were developed by sampling from the probability distribution with a weighted a-posteriori error estimator for the construction of the reduced basis space. Structured sampling methods using quadrature/collocation points such as Chebyshev points and Gauss Legendre/Hermite points have also been investigated [27] in comparison with the random sampling methods.…”

“…Many different methods are available to solve such problems numerically, such as stochastic Galerkin [22], stochastic collocation [1,17,25], as well as Monte-Carlo [22]. More recently, methods based on reduced order models have been developed [6,7,8,11,21,23]. In practice, they aim to construct low-dimensional approximation subspaces in a weighted fashion, i.e.…”
