Constructor Detail

FactorObserved

public FactorObserved(Factor f1,
                      Variable[] observedVars,
                      int[] observedVals)

constructs a factor with the given obsevations.

Parameters:

f1 - the factor that is to be updated

observedVars - the array of variables that have observed values. These are assumed to be in order. They do not necessarily appear in f1.

ObservedVals - the array of values for the corresponding observed values. Each value ObservedVals[i] is the index into ObservedVars[i].getDomain().
