Abstract:
In recent years piecewise deterministic Markov processes (PDMPs) have
emerged as a promising alternative to classical MCMC algorithms. In
particular these PDMP based algorithms have good convergence properties
and allow for efficient subsampling.
Although many different PDMP based algorithms can be designed, two
algorithms play fundamental roles: the Bouncy Particle sampler and the
Zig-Zag sampler.
In this talk both algorithms will be introduced and a comparison of
properties of these algorithms will be presented, including recent
results on ergodicity and on scaling with respect to dimension.
