HiddenMarkov

The HiddenMarkov classes provides Hidden Markov Models (HMM). An HMM model consists of a probability vector 'pi' and probability matrices 'a' and 'b'. The discrete-time system is characterized by a hidden 'state(t)' and an 'observed(t)' symbol at time 't'.

pi(j) = P(state(t) = j) a(i, j) = P(state(t+1) = j|state(t) = i) b(i, k) = P(observed(t) = k|state(t) = i)
