Connecting the Dots: Numerical Randomized Hamiltonian Monte Carlo with State-Dependent Event Rates
(Peer reviewed; Journal article, 2022)Numerical generalized randomized Hamiltonian Monte Carlo is introduced, as a robust, easy to use and computationally fast alternative to conventional Markov chain Monte Carlo methods for continuous target distributions. A ... -
Importance Sampling-based Transport Map Hamiltonian Monte Carlo for Bayesian Hierarchical Models
(Peer reviewed; Journal article, 2021-06)We propose an importance sampling (IS)-based transport map Hamiltonian Monte Carlo procedure for performing a Bayesian analysis in nonlinear high-dimensional hierarchical models. Using IS techniques to construct a transport ... -
Statistical analysis of locally parameterized shapes
(Peer reviewed; Journal article, 2022)In statistical shape analysis, the establishment of correspondence and defining shape representation are crucial steps for hypothesis testing to detect and explain local dissimilarities between two groups of objects. Most ...
