Budget-limited distribution learning in multifidelity problems
Yiming Xu, Akil Narayan
Multifidelity methods are widely used for estimating quantities of interest (QoI) in computational science by employing numerical simulations of differing costs and accuracies. Man…

Randomized weakly admissible meshes
Yiming Xu, Akil Narayan
A weakly admissible mesh (WAM) on a continuum real-valued domain is a sequence of discrete grids such that the discrete maximum norm of polynomials on the grid is comparable to the…
