Constructor

Parameters:

evaluator - An instance of miope.classifier.WekaClassificationStrategy.AttributeEvaluator
search_method - An instance of miope.classifier.WekaClassificationStrategy.SearchMethod
classifier_weka - A element of ClassifierWekaPath or an instance of miope.classifier.MetraStrategy
path_weka - A path to the weka.jar. None if weka is in your classpath
cl_params - A string. It specifies the configuration of the WEKA classifier. See WEKA command line options for a detailed explanation.
model - A path to a trained model (SOMETHING.model). If None, a model must be trained using train() method.

Overrides: object.__init__

meta_information(self, meta_information_file)

source code

Parameters:

meta_information_file - A string. The path to output file provided by WEKA after training the model. @return A dictionary with meta information about the classifier.
