CiteSeerX — The Hierarchical Hidden Markov Model: Analysis and Applications
... For simplicity, the pro- duction states are omitted from the gure. To summarize, a string is generated by starting from the root state and choosing one of the root's substates at random according to q 1 . Similarly, ...
