On the Forgetting of Particle Filters

Joona Karjalainen, Anthony Lee, Sumeetpal S. Singh +1

We study the forgetting properties of the particle filter when its state - the collection of particles - is regarded as a Markov chain. Under a strong mixing assumption on the part…

Adaptive Riemannian Manifold Hamiltonian Monte Carlo with Hierarchical Metric

Miika Kailas, Matti Vihola, Jonas Wallin

Hamiltonian Monte Carlo (HMC) and its dynamic extensions, such as the No-U-Turn Sampler (NUTS), are powerful Markov chain Monte Carlo methods for sampling from complex, high-dimens…

On the complexity of standard and waste-free SMC samplers

Yvann Le Fay, Nicolas Chopin, Matti Vihola

We establish finite sample bounds for the error of standard and waste-free SMC samplers. Our results cover estimates of both expectations and normalising constants of the target di…

Iterated sampling importance resampling with adaptive number of proposals

Pietari Laitinen, Matti Vihola

Iterated sampling importance resampling (i-SIR) is a Markov chain Monte Carlo (MCMC) algorithm which is based on independent proposals. As grows, its samples become nearly…

Mixing time of the conditional backward sampling particle filter

Joona Karjalainen, Anthony Lee, Sumeetpal S. Singh +1

The conditional backward sampling particle filter (CBPF) is a powerful Markov chain Monte Carlo sampler for general state space hidden Markov model (HMM) smoothing. It was proposed…
