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

S Hayakawa, T Lyons, H Oberhauser - Probability Theory and Related …, 2023 - Springer
For ad-dimensional random vector X, let pn, X (θ) be the probability that the convex hull of n
independent copies of X contains a given point θ. We provide several sharp inequalities …

Monte Carlo cubature construction

S Hayakawa - Japan Journal of Industrial and Applied Mathematics, 2021 - Springer
In numerical integration, cubature methods are effective, especially when the integrands can
be well-approximated by known test functions, such as polynomials. However, the …

Hypercontractivity meets random convex hulls: analysis of randomized multivariate cubatures

S Hayakawa, H Oberhauser… - Proceedings of the …, 2023 - royalsocietypublishing.org
Given a probability measure μ on a set X and a vector-valued function φ, a common problem
is to construct a discrete probability measure on X such that the push-forward of these two …

High-degree cubature on Wiener space through unshuffle expansions

E Ferrucci, T Herschell, C Litterer, T Lyons - arxiv preprint arxiv …, 2024 - arxiv.org
Utilising classical results on the structure of Hopf algebras, we develop a novel approach for
the construction of cubature formulae on Wiener space based on unshuffle expansions. We …

Total variation bound for Milstein scheme without iterated integrals

T Yamada - Monte Carlo Methods and Applications, 2023 - degruyter.com
The paper gives new results for the Milstein scheme of stochastic differential equations. We
show that (i) the Milstein scheme holds as a weak approximation in total variation sense and …
