Serializable, org.apache.flink.ml.api.AlgoOperator<BinaryClassificationEvaluator>, org.apache.flink.ml.api.Stage<BinaryClassificationEvaluator>, org.apache.flink.ml.common.param.HasLabelCol<BinaryClassificationEvaluator>, org.apache.flink.ml.common.param.HasRawPredictionCol<BinaryClassificationEvaluator>, org.apache.flink.ml.common.param.HasWeightCol<BinaryClassificationEvaluator>, BinaryClassificationEvaluatorParams<BinaryClassificationEvaluator>, org.apache.flink.ml.param.WithParams<BinaryClassificationEvaluator>

public class BinaryClassificationEvaluator
extends Object
implements org.apache.flink.ml.api.AlgoOperator<BinaryClassificationEvaluator>, BinaryClassificationEvaluatorParams<BinaryClassificationEvaluator>

An AlgoOperator which calculates the evaluation metrics for binary classification. The input data has columns rawPrediction, label and an optional weight column. The rawPrediction can be of type double (binary 0/1 prediction, or probability of label 1) or of type vector (length-2 vector of raw predictions, scores, or label probabilities). The output may contain different metrics which will be defined by parameter MetricsNames. See BinaryClassificationEvaluatorParams.
