The dual IRLS scheme for (hyper-)graph $p$ -Laplacians and $ℓ^{p}$ regression with large exponents

Johannes Storn

We introduce an iterative scheme for discrete convex minimization problems of $p$ -Laplace type such as variational graph $p$ -Laplace problems and $ℓ^{p}$ regression. In each itera…

Randomized Projection Operators onto Piecewise Polynomial Spaces

Johannes Storn

We introduce computable projection operators onto piecewise polynomial spaces, defined via sampling and discrete least-squares polynomial approximations. The resulting mappings exh…
