Differential privacy guarantees of Markov chain Monte Carlo algorithms

Andrea Bertazzi, Tim Johnston, Gareth O. Roberts +1

This paper aims to provide differential privacy (DP) guarantees for Markov chain Monte Carlo (MCMC) algorithms. In a first part, we establish DP guarantees on samples output by MCM…

Sampling with time-changed Markov processes

Andrea Bertazzi, Giorgos Vasdekis

We study time-changed Markov processes to speed up the convergence of Markov chain Monte Carlo (MCMC) algorithms. The time-changed process is defined by adjusting the speed of time…

Piecewise deterministic generative models

Andrea Bertazzi, Dario Shariatian, Umut Simsekli +2

We introduce a novel class of generative models based on piecewise deterministic Markov processes (PDMPs), a family of non-diffusive stochastic processes consisting of deterministi…

Piecewise deterministic sampling with splitting schemes

Andrea Bertazzi, Paul Dobson, Pierre Monmarché

We introduce Markov chain Monte Carlo (MCMC) algorithms based on numerical approximations of piecewise-deterministic Markov processes obtained with the framework of splitting schem…

Approximations of Piecewise Deterministic Markov Processes and their convergence properties

Andrea Bertazzi, Joris Bierkens, Paul Dobson

Piecewise deterministic Markov processes (PDMPs) are a class of stochastic processes with applications in several fields of applied mathematics spanning from mathematical modeling…

Adaptive schemes for piecewise deterministic Monte Carlo algorithms

Andrea Bertazzi, Joris Bierkens

The Bouncy Particle sampler (BPS) and the Zig-Zag sampler (ZZS) are continuous time, non-reversible Monte Carlo methods based on piecewise deterministic Markov processes. Experimen…
