Positively Weighted Kernel Quadrature via Subsampling

Satoshi Hayakawa, Harald Oberhauser, Terry Lyons

We study kernel quadrature rules with convex weights. Our approach combines the spectral properties of the kernel with recombination results about point measures. This results in e…

Estimating the probability that a given vector is in the convex hull of a random sample

Satoshi Hayakawa, Terry Lyons, Harald Oberhauser

For a $d$ -dimensional random vector $X$ , let $p_{n, X} (θ)$ be the probability that the convex hull of $n$ independent copies of $X$ contains a given point $θ$ . We provide several s…
