Recall the hidden Markov model (HMM). a finite state automata with nodes that represent hidden states (that is, things we cannot necessarily observe, but must infer from data) and two sets of links. transition – probability that this state will follow from the previous state.

Probability as a subjective measure of degree of belief or credences constrained by principles of rationality (the axioms of probability and sometimes other constraints e.g. indifference)..
