Particle filtering for continuous-time hidden Markov models
2007
ESAIM: Proceedings and Surveys
We consider continuous-time models where the observed process depends on an unobserved jump Markov Process. We develop a sequential Monte Carlo algorithm which makes it possible to filter and smooth this latent process, and compute the likelihood pointwise. We develop a Rao-Blackwellisation technique which allows to significantly reduce the Monte Carlo noise of this algorithm. Possible extensions of our algorithm and further directions of research are discussed. * We are grateful to Tobyas Ryden for helpful comments.
