Hidden Markov random field

A hidden Markov random field is a generalization of a hidden Markov model. Instead of having an underlying Markov chain, hidden Markov random fields have an underlying Markov random field.

Hidden Markov random field The result of stochastically perturbing the variables in a Markov random field (the original variables are thus "hidden"). The result is technically still a Markov random field, but some variables are never observed.
