[Abstract] The e-Machine is a hidden Markov model generalization that does not require a priori knowledge of the state structure of a system or the transition probabilities between the states. In this work, we discuss how e-Machines are used to locate and analyze behavioral patterns in symbolized input data streams. We explain how the e-Machine can be used to recognize when certain patterns occur.
