Probabilistic finite-state machines - Part II.

Abstract : Probabilistic finite-state machines are used today in a variety of areas in pattern recognition, or in fields to which pattern recognition is linked. In part I of this paper, we surveyed these objects and studied their properties. In this part II, we study the relations between probabilistic finite-state automata and other well known devices that generate strings like hidden Markov models and - grams, and provide theorems, algorithms and properties that represent a current state of the art of these objects.
