public interface DiscreteObservationFunction extends ObservationFunction
ObservationFunction
for the case when the set of observations are
discrete and able to be enumerated. Requires implementing the allObservations()
method and
probabilities(State, Action)
method. The former should return all possible observations; the
latter should return the set of observations with nonzero probability and their probabilities, for a given
input hidden state and action that led to the hidden state.Modifier and Type  Method and Description 

java.util.List<State> 
allObservations()
Returns a
List containing all possible observations. 
java.util.List<ObservationProbability> 
probabilities(State state,
Action action)
Returns the observation probability mass/density function for all observations that have nonzero mass/density conditioned on the true MDP state and previous action taken that led to the state.
