Class ManyVsRestLearner

java.lang.Object
  edu.cmu.minorthird.classify.OneVsAllLearner
      edu.cmu.minorthird.classify.ManyVsRestLearner

All Implemented Interfaces:

ClassifierLearner, java.lang.Cloneable

public class ManyVsRestLearner
extends OneVsAllLearner

Multi-class version of a binary classifier; Generalizes OneVsAllLearner. OneVsAll allows one class with positive labels for each example, and the rest with negative labels. In ManyVsRest, in each example many classes may be positive.

Method Detail

copy

public ClassifierLearner copy()

Description copied from interface: ClassifierLearner

Make a copy of the learner. Note: This will reset the learner, erasing previous data!

Specified by:

copy in interface ClassifierLearner

Overrides:

copy in class OneVsAllLearner

addExample

public void addExample(Example answeredQuery)

Description copied from interface: ClassifierLearner

Accept a labeled example. The example might be the answer to the last query, or it may be an example chosen by the teacher.

All learners must provide a non-trivial implementation of addExample.

Specified by:

addExample in interface ClassifierLearner

Overrides:

addExample in class OneVsAllLearner
