    Implement the apply method of Classifier by transforming the tuples into Liblinear Features and then calling Linear.predictProbability.

    TODO: This should be made more general so that the SVM solvers can be used by Nak.

  13. def evalIndexed(observations: Seq[FeatureObservation[Int]]): Array[Double]

    Evaluate the given indexed feature observations.

    Evaluate the given indexed feature observations. Calls the apply method, which must interface with some underlying representation of the system used; e.g. see the LiblinearClassifier class.

  14. def evalUnindexed(observations: Seq[FeatureObservation[String]]): Array[Double]

    Evaluate the un-indexed feature observations.

    Evaluate the un-indexed feature observations. Uses the feature map to index the observations and then pass them on to evalIndexed of Classifier.
