      className - The class name.
      message - The serialized data.
      Returns:
      The deserialized object.

    • convertOutput

      public Prediction<Regressor> convertOutput(DenseVector scores, int numValidFeature, Example<Regressor> example, ImmutableOutputInfo<Regressor> outputIDInfo)
      Description copied from interface: OCIOutputConverter
      Converts a dense vector into a single prediction of the appropriate type.
      Specified by:
      convertOutput in interface OCIOutputConverter<Regressor>
      Parameters:
      scores - The score vector.
      numValidFeature - The number of valid features (stored in the prediction).
      example - The example (stored in the prediction).
      outputIDInfo - The output information.
      Returns:
      A prediction representing the value of this score vector.

    • convertOutput

      public List<Prediction<Regressor>> convertOutput(DenseMatrix scores, int[] numValidFeatures, List<Example<Regressor>> examples, ImmutableOutputInfo<Regressor> outputIDInfo)
      Description copied from interface: OCIOutputConverter
      Converts a dense matrix into a list of predictions of the appropriate type.
      Specified by:
      convertOutput in interface OCIOutputConverter<Regressor>
      Parameters:
      scores - The score matrix.
      numValidFeatures - The number of valid features in each example (stored in the prediction).
      examples - The examples (stored in the prediction).
      outputIDInfo - The output information.
      Returns:
      A list of predictions representing the value of this score matrix.

    • generatesProbabilities

      public boolean generatesProbabilities()
      Description copied from interface: OCIOutputConverter
      Does this OCIOutputConverter generate probabilities?
      Specified by:
      generatesProbabilities in interface OCIOutputConverter<Regressor>
      Returns:
      True if it produces a probability distribution in the Prediction.

    • getTypeWitness

      public Class<Regressor> getTypeWitness()
      Description copied from interface: OCIOutputConverter
      The type witness used when deserializing the OCI model from a protobuf.

      The default implementation throws UnsupportedOperationException for compatibility with implementations which don't use protobuf serialization. This implementation will be removed in the next major version of Tribuo.

      Specified by:
      getTypeWitness in interface OCIOutputConverter<Regressor>
      Returns:
      The output class this object produces.
