. High dimensional distributions, especially those with heavy tails, are notoriously difficult for off the shelf MCMC samplers: the combination of unbounded state spaces, diminishing gradient information, and local moves, results in empirically observed ”stickiness” and poor theoretical mixing properties – lack of geometric ergodicity. In this paper, we introduce a new class of MCMC samplers that map the original high dimensional problem in Euclidean space onto a sphere and remedy these notorious… 


Dimension-independent Markov chain Monte Carlo on the sphere
Efficient Markov chain Monte Carlo methods are derived for approximate sampling of posteriors with respect to high-dimensional spheres with angular central Gaussian priors, which show dimension-independent efficiency in numerical experiments.
Convergence of Heavy‐tailed Monte Carlo Markov Chain Algorithms
The paper gives for the first time a theoretical justification for the common belief that heavy‐tailed proposal distributions improve convergence in the context of random‐walk Metropolis algorithms.
Exponential ergodicity of the bouncy particle sampler
Non-reversible Markov chain Monte Carlo schemes based on piecewise deterministic Markov processes have been recently introduced in applied probability, automatic control, physics and statistics.
High-dimensional scaling limits of piecewise deterministic sampling algorithms
Scaling limits for bothiecewise deterministic Markov processes are determined and based on these scaling limits the performance of the two algorithms in high dimensions can be compared.
Geometric ergodicity of the Bouncy Particle Sampler
The Bouncy Particle Sampler (BPS) is a Monte Carlo Markov Chain algorithm to sample from a target density known up to a multiplicative constant. This method is based on a kinetic piecewise
Hypocoercivity of piecewise deterministic Markov process-Monte Carlo
In this work, we establish $\mathrm{L}^2$-exponential convergence for a broad class of Piecewise Deterministic Markov Processes recently proposed in the context of Markov Process Monte Carlo methods
Geometric convergence and central limit theorems for multidimensional Hastings and Metropolis algorithms
We develop results on geometric ergodicity of Markov chains and apply these and other recent results in Markov chain theory to multidimensional Hastings and Metropolis algorithms. For those based on
Monte Carlo on Manifolds: Sampling Densities and Integrating Functions
An MCMC sampler is given for probability distributions defined by unnormalized densities on manifolds in euclidean space defined by equality and inequality constraints and used to develop a multistage algorithm to compute integrals over such manifolds.
Randomized Hamiltonian Monte Carlo as scaling limit of the bouncy particle sampler and dimension-free convergence rates
The Bouncy Particle Sampler is a Markov chain Monte Carlo method based on a nonreversible piecewise deterministic Markov process. In this scheme, a particle explores the state space of interest by
The Bouncy Particle Sampler: A Nonreversible Rejection-Free Markov Chain Monte Carlo Method
An alternative scheme recently introduced in the physics literature where the target distribution is explored using a continuous-time nonreversible piecewise-deterministic Markov process is explored, and several computationally efficient implementations of this Markov chain Monte Carlo schemes are proposed.
