....issue is how to efficiently compute the sampling distribution P (R t jy 1:T ; r (k) t ) CK96] propose an O(T ) algorithm which involves first running the backwards Kalman filter 1 , and then working forwards, sampling R t and doing Bayesian updating conditional on the sampled value. See [DA99] for some slight improvements. Both papers are difficult to read because of the heavy notation involved in explicitely manipulating Gaussians. Here, we rederive the algorithm for the simpler case in which X is a discrete random variable. Y can have an arbitrary distribution, since it is ....

....MCMC sampler by anaylitcal integration w.r.t. the continuous valued state sequence XN and Monte Carlo integration w.r.t. the association sequence N . Techniques similar to those presented in this work have been used for estimation of parameters of jump Markov linear systems described in [4, 5]. In summary, the proposed algorithm is a Gibbs sampler with the following structure. 1. Pick the initial association (0) N = f (0) t g N t=0 randomly or deterministically. Set p = 1. 2. For each t = 0; 1; N generate a random sample from the full conditional distribution (p) t ....
....a backwards information filter at item 4 are therefore reused at item 2 in the next iteration. Instead of sampling from the full conditional in item 3(b) above, MMAP estimates can be formed by deterministically picking the most likeliy association, according to the Iterated Conditional Mode (ICM) [4]. The resulting ICMDA algorithm is iterated until two subsequent passes yields the same association sequence. 4. PREVIOUS APPROACHES 4.1.
