Method Detail

defineOptions

public void defineOptions()

Adds options to the internal list of options.

Specified by:

defineOptions in interface OptionHandler

Overrides:

defineOptions in class AbstractOptionHandler

setStrictCapabilities

public void setStrictCapabilities(boolean value)

Sets whether to use a strict capabilities check.

Parameters:

value - true if to use strict check

getStrictCapabilities

public boolean getStrictCapabilities()

Returns whether to use a strict capabilities check.

Returns:

true if to use strict check

strictCapabilitiesTipText

public String strictCapabilitiesTipText()

Returns the tip text for this property.

Returns:

tip text for this property suitable for displaying in the GUI or for listing the options.

getCapabilities

public Capabilities getCapabilities()

Returns the algorithm's capabilities in terms of data.

Specified by:

getCapabilities in interface Algorithm<MultiTargetRegressionModel>

Specified by:

getCapabilities in interface CapabilitiesHandler

Returns:

the algorithm's capabilities

handles

public String handles(Dataset data,
                      boolean strict)

Checks whether the data can be handled.

Specified by:

handles in interface Algorithm<MultiTargetRegressionModel>

Parameters:

data - the data to check

strict - whether to perform a strict check

Returns:

null if data can be handled, otherwise error message

check

protected Dataset check(Dataset data)
                 throws Exception

Builds a model from the data.

Parameters:

data - the data to use for building the model

Returns:

the generated model

Throws:

Exception - if the build fails

buildModel

public MultiTargetRegressionModel buildModel(Dataset data)
                                      throws Exception
