# 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)

### __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
