    • getNumberOfSupportVectors

      public int getNumberOfSupportVectors()
      Returns the number of support vectors.
      Returns:
      The number of support vectors.

    • predict

      public Prediction<Event> predict(Example<Event> example)
      Description copied from class: Model
      Uses the model to predict the output for a single example.

      predict does not mutate the example.

      Throws IllegalArgumentException if the example has no features or no feature overlap with the model.

      Specified by:
      predict in class Model<Event>
      Parameters:
      example - the example to predict.
      Returns:
      the result of the prediction.

    • copy

      protected LibSVMAnomalyModel copy(String newName, ModelProvenance newProvenance)
      Description copied from class: Model
      Copies a model, replacing its provenance and name with the supplied values.

      Used to provide the provenance removal functionality.

      Specified by:
      copy in class Model<Event>
      Parameters:
      newName - The new name.
      newProvenance - The new provenance.
      Returns:
      A copy of the model.
