Web1 de mar. de 2016 · It is only the outcome, not the state visible to an external observer and therefore states are “hidden” to the outside, hence the name Hidden Markov Model. … Web1 de mar. de 2016 · The Hidden Markov Model is a finite set of states, each of which is associated with a (generally multidimensional) probability distribution. Transitions among the states are governed by a set of probabilities called transition probabilities.
