Constructor Detail

UncertainSplitFilter

public UncertainSplitFilter(int dims)

Constructor.

Parameters:

dims - Number of dimensions

Method Detail

filterSingleObject

protected UnweightedDiscreteUncertainObject filterSingleObject(NumberVector vec)

Description copied from class: AbstractConversionFilter

Normalize a single instance. You can implement this as UnsupportedOperationException if you override both public "normalize" functions!

Specified by:

filterSingleObject in class AbstractConversionFilter<NumberVector,UnweightedDiscreteUncertainObject>

Parameters:

vec - Database object to normalize

Returns:

Normalized database object

getInputTypeRestriction

protected SimpleTypeInformation<? super NumberVector> getInputTypeRestriction()

Description copied from class: AbstractConversionFilter

Get the input type restriction used for negotiating the data query.

Specified by:

getInputTypeRestriction in class AbstractConversionFilter<NumberVector,UnweightedDiscreteUncertainObject>

Returns:

Type restriction

convertedType

protected SimpleTypeInformation<UnweightedDiscreteUncertainObject> convertedType(SimpleTypeInformation<NumberVector> in)

Description copied from class: AbstractConversionFilter

Get the output type from the input type after conversion.

Specified by:

convertedType in class AbstractConversionFilter<NumberVector,UnweightedDiscreteUncertainObject>

Parameters:

in - input type restriction

Returns:

output type restriction

getLogger

protected Logging getLogger()

Description copied from class: AbstractConversionFilter

Class logger.

Specified by:

getLogger in class AbstractConversionFilter<NumberVector,UnweightedDiscreteUncertainObject>

Returns:

Logger
