Class MulticlassClassifier

source code

CombinedClassifier to perform multiclass using a list of BinaryClassifier.

such as 1-vs-1 (ie in pairs like libsvm doesn) or 1-vs-all (which is yet to think about)

Method Details [hide private]

__init__(self, clf, bclf_type="1-vs-1", **kwargs)
(Constructor)

source code 
Initialize the instance
Parameters:
  • clf (Classifier) - classifier based on which multiple classifiers are created for multiclass
  • bclf_type - "1-vs-1" or "1-vs-all", determines the way to generate binary classifiers
Overrides: object.__init__

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

source code 
Literal representation of CombinedClassifier.
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 classifier
Overrides: base.Classifier._train
