  • Method Details

    • predict

      public Prediction<MultiLabel> predict(Example<MultiLabel> 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<MultiLabel>
      Parameters:
      example - the example to predict.
      Returns:
      the result of the prediction.

    • getDimensionName

      protected String getDimensionName(int index)
      Description copied from class: AbstractFMModel
      Gets the name of the indexed output dimension.
      Specified by:
      getDimensionName in class AbstractFMModel<MultiLabel>
      Parameters:
      index - The output dimension index.
      Returns:
      The name of the requested output dimension.

    • copy

      protected FMMultiLabelModel 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<MultiLabel>
      Parameters:
      newName - The new name.
      newProvenance - The new provenance.
      Returns:
      A copy of the model.

    • onnxModelName

      protected String onnxModelName()
      Specified by:
      onnxModelName in class AbstractFMModel<MultiLabel>
      Returns:
      Name to write into the ONNX Model.

    • onnxOutput

      protected ONNXNode onnxOutput(ONNXNode input)
      Description copied from class: AbstractFMModel
      Takes the unnormalized ONNX output of this model and applies an appropriate normalizer from the concrete class.
      Specified by:
      onnxOutput in class AbstractFMModel<MultiLabel>
      Parameters:
      input - Unnormalized ONNX leaf node.
      Returns:
      Normalized ONNX leaf node.
