Class SerializedClassifier

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable, CapabilitiesHandler, OptionHandler, RevisionHandler
    public class SerializedClassifier
extends Classifier
    A wrapper around a serialized classifier model. This classifier loads a serialized models and uses it to make predictions.

    Warning: since the serialized model doesn't get changed, cross-validation cannot bet used with this classifier.

    Valid options are: 

     -D
  If set, classifier is run in debug mode and
  may output additional info to the console
     -model <filename>
  The file containing the serialized model.
  (required)
