Method Detail

preProcess

protected Map<String,Object> preProcess(Map<String,Object> data)

Returns the processed data (e.g. perform categorisation, etc). If no processing is needed, simply return the original data.

Specified by:

preProcess in class AbstractPMMLBackend

Parameters:

data - A map containing the input data, with attribute names as key and values as values.

Returns:

data A map containing the processed data, with attribute names as key and values as values.

getIdentifier

public String getIdentifier()

predict

public org.kie.internal.task.api.prediction.PredictionOutcome predict(org.kie.api.task.model.Task task,
                                                                      Map<String,Object> data)

Returns a model prediction given the input data

Parameters:

task - Human task data

data - A map containing the input attribute names as keys and the attribute values as values.

Returns:

A PredictionOutcome containing the model's prediction for the input data.
