Multilevel higher order Quasi-Monte Carlo Bayesian Estimation
Josef Dick, Robert N. Gantner, Quoc T. Le Gia +1
We propose and analyze deterministic multilevel approximations for Bayesian inversion of operator equations with uncertain distributed parameters, subject to additive Gaussian meas…
Lattice based integration algorithms: Kronecker sequences and rank-1 lattices
Josef Dick, Friedrich Pillichshammer, Kosuke Suzuki +2
We prove upper bounds on the order of convergence of lattice based algorithms for numerical integration in function spaces of dominating mixed smoothness on the unit cube with homo…
Computationally Efficient Bayesian Estimation of High Dimensional Copulas with Discrete and Mixed Margins
D. Gunawan, M. -N. Tran, K. Suzuki +2
Estimating copulas with discrete marginal distributions is challenging, especially in high dimensions, because computing the likelihood contribution of each observation requires ev…
On the optimal order of integration in Hermite spaces with finite smoothness
Josef Dick, Christian Irrgeher, Gunther Leobacher +1
We study the numerical approximation of integrals over with respect to the standard Gaussian measure for integrands which lie in certain Hermite spaces of functions.…
Discrepancy of second order digital sequences in function spaces with dominating mixed smoothness
Josef Dick, Aicke Hinrichs, Lev Markhasin +1
The discrepancy function measures the deviation of the empirical distribution of a point set in from the uniform distribution. In this paper, we study the classical discr…
Higher order Quasi-Monte Carlo integration for Bayesian Estimation
Josef Dick, Robert N. Gantner, Quoc T. Le Gia +1
We analyze combined Quasi-Monte Carlo quadrature and Finite Element approximations in Bayesian estimation of solutions to countably-parametric operator equations with holomorphic d…
