double kddml.Operators.Preprocessing.NormalizationAlgorithms.NormalizationAlgorithmResolverTask.normalize double  value  )  throws ResolverException
 

Normalizes the input value according to the normalization technique. Returns the normalized value.

Parameters:
value double
Returns:
double
Exceptions:
ResolverException 

Implemented in kddml.Operators.Preprocessing.NormalizationAlgorithms.MIN_MAX_NORMALIZATION_RESOLVER, and kddml.Operators.Preprocessing.NormalizationAlgorithms.Z_SCORE_NORMALIZATION_RESOLVER.

void kddml.Operators.Preprocessing.NormalizationAlgorithms.NormalizationAlgorithmResolverTask.readNormalizationAttributeStatistics NumericalStatisticManager  stat  )  throws ResolverException, KDDMLCoreException
 

Reads the data statistics related to the input normalization attribute. Data statistic can be used to provide additional information to preprocessing algorithm, such as the minimum and maximum value of the attribute.

Parameters:
stat NumericalStatisticManager
Exceptions:
ResolverException 
KDDMLCoreException 

Implemented in kddml.Operators.Preprocessing.NormalizationAlgorithms.MIN_MAX_NORMALIZATION_RESOLVER, and kddml.Operators.Preprocessing.NormalizationAlgorithms.Z_SCORE_NORMALIZATION_RESOLVER.
