WebA Hidden Markov Model can be used to study phenomena in which only a portion of the phenomenon can be directly observed while the rest of it is hidden from direct view. The effect of the unobserved portion can only be estimated. We represent such phenomena using a mixture of two random processes. One of the two processes is a ‘ visible process ’.
