Method Details

evaluate

public Map<String,Double> evaluate(MultiCTBNC<?,?> model)
                            throws UnreadDatasetException,
ErroneousValueException

Evaluates the performance of the specified model using cross-validation.

Specified by:

evaluate in class ValidationMethod

Parameters:

model - model to evaluate

Returns:

the results of the cross-validation in a Map

Throws:

UnreadDatasetException - if the provided dataset could not be read

ErroneousValueException - if a provided parameter is erroneous for the requested task

evaluate

public Map<String,Double> evaluate(MultiCTBNC<?,?> model,
 double preprocessingExecutionTime)
                            throws UnreadDatasetException,
ErroneousValueException

Description copied from class: ValidationMethod

Evaluates the performance of the specified model and returns the results. This method receives the execution time of previous tasks so it is add up to the total mean learning time.

Specified by:

evaluate in class ValidationMethod

Parameters:

model - model to evaluate

preprocessingExecutionTime - execution time of previous tasks

Returns:

results saved in a Map.

Throws:

UnreadDatasetException - if there was an error while reading a dataset

ErroneousValueException - if a provided parameter is erroneous for the requested task
