Detailed Description

Interface for computing emission probabilities in a Hidden Markov Model.

This class is part of the HMM framework. It compute the probabilities of the data conditionned on each hidden state. The emission probabilities class also has in charge the data, its putative compression, and the number of position in the sequence of observed states.
