public interface MaxEntGEConstraint
Interface for expectation constraints for use with Generalized Expectation (GE).
Method Summary | |
---|---|
void |
computeExpectations(FeatureVector fv,
double[] dist,
double weight)
Compute expectations using provided distribution over labels. |
double |
getCompositeConstraintFeatureValue(FeatureVector input,
int label)
Computes the composite constraint feature value (over all constraint features) for FeatureVector fv and label label. |
double |
getValue()
Returns the total constraint value. |
void |
preProcess(FeatureVector input)
Gives the constraint the option to do some caching using only the FeatureVector. |
java.util.BitSet |
preProcess(InstanceList data)
|
void |
zeroExpectations()
Zero expectation values. |
