This class can be used to calculate the AUC of a binary classification model, as well as. This also provides an internal param map to store parameter values attached to the instance. Abstract class for transformers that take one input column, apply transformation, and output the result as a new column3 Methods. evaluation import BinaryClassificationEvaluator evaluator = BinaryClassificationEvaluator(labelCol='Survived', metricName='areaUnderROC') Apache Spark, once a component of the Hadoop ecosystem, is now becoming the big-data platform of choice for enterprises. This is useful because the curve contains a point for each. here is my Parameter grid build code. The rawPrediction column can be of type double (binary 0/1 prediction, or probability.
