Deprecated.

Constructor for class BitVectorAttributeModel.

Parameters:

attributeName - the name of the attribute

skipMissingVals - set to true if the missing values should be skipped during learning and prediction

BitVectorAttributeModel

public BitVectorAttributeModel(String attributeName,
                               boolean skipMissingVals,
                               int noOfMissingVals,
                               Config config)
                        throws InvalidSettingsException

Deprecated.

Constructor for class BitVectorAttributeModel.

Parameters:

attributeName - the name of the attribute

skipMissingVals - set to true if the missing values should be skipped during learning and prediction

noOfMissingVals - the number of missing values

config - the Config object to read from

Throws:

InvalidSettingsException - if the settings are invalid

Method Detail

saveModelInternal

void saveModelInternal(Config config)

Deprecated.

Specified by:

saveModelInternal in class AttributeModel

Parameters:

config - the config object to save to

validate

void validate()
       throws InvalidSettingsException

Deprecated.

Called after all training rows where added to validate the model.

Specified by:

validate in class AttributeModel

Throws:

InvalidSettingsException - if the model isn't valid

getType

String getType()

Deprecated.

Specified by:

getType in class AttributeModel

Returns:

the unique type of the model

Deprecated.

Specified by:

getCompatibleType in class AttributeModel

Returns:

the DataValue class to check if the rows are compatible

addValueInternal

void addValueInternal(String classValue,
                      DataCell attrValue)
               throws TooManyValuesException

Deprecated.

Adds the given value to the concrete implementation. Should handle missing values as well.

Specified by:

addValueInternal in class AttributeModel

Parameters:

classValue - the class value

attrValue - the attribute value. Could be a missing value.
