Our method builds on the particle Gibbs (PG) sampler proposed by Andrieu et al. (2010). In PG, the aforementioned Markov kernel is constructed by running an SMC.
Jan 3, 2014 · The ancestor sampling procedure enables fast mixing of the PGAS kernel even when using seemingly few particles in the underlying SMC sampler.
We present a novel method in the family of particle MCMC methods that we refer to as particle Gibbs with ancestor sampling (PG-AS). Similarly to the existing PG ...

Based on a PF ⇒ approximate sample. • Does not leave p(B,x1:T | y1:T) invariant! • Relies on large N to be successful. • A lot of wasted computations.
