Method Details [hide private]

__init__(self, clf, poslabels, neglabels, **kwargs)
(Constructor)

source code 
Initialize the instance
Parameters:
  • clf (Classifier) - classifier to use
  • poslabels (list) - list of labels which are treated as +1 category
  • neglabels (list) - list of labels which are treated as -1 category
Overrides: object.__init__

__repr__(self, prefixes=[])
(Representation operator)

source code 
String definition of the object of ClassWithCollections object
Parameters:
  • fullname - Either to include full name of the module
  • prefixes - What other prefixes to prepend to list of arguments
Overrides: object.__repr__
(inherited documentation)

_train(self, dataset)

source code 
Train BinaryClassifier
Overrides: base.Classifier._train

_predict(self, data)

source code 

Predict the labels for a given data

Predicts using binary classifier and spits out list (for each sample) where with either poslabels or neglabels as the "label" for the sample. If there was just a single label within pos or neg labels then it would return not a list but just that single label.

Overrides: base.Classifier._predict
