Abstract—Hidden Markov Models (HMMs) have become increasingly popular in recent years in a wide range of applications. Special subclasses of HMMs have been ...
More precisely we show that a partially exchangeable sequence is a countable HMM if and only if it is a countable mixture of Markov chains. Our main theorem ...
exchangeable when x is the true hidden sequence, S(I) is equally ... is a mixture of Markov chains, it is partially exchangeable according to Theorem 3.1.
We prove a uniformly computable version of de Finetti's theorem on exchangeable sequences of real random variables. As a consequence, exchangeable stochastic ...
