Function recovery and optimal sampling in the presence of nonuniform evaluation costs
Ben Adcock
We consider recovering a function in an -dimensional linear subspace from i.i.d. pointwise samples via (weighted) least-squares esti…

Optimal sampling for least-squares approximation
Ben Adcock
Least-squares approximation is one of the most important methods for recovering an unknown function from data. While in many applications the data is fixed, in many others there is…
