Class | Description |
---|---|
BinaryClassificationEvaluator |
Evaluator for binary classification, which expects input columns rawPrediction, label and
an optional weight column.
|
ClusteringEvaluator |
Evaluator for clustering results.
|
ClusteringMetrics |
Metrics for clustering, which expects two input columns: prediction and label.
|
CosineSilhouette |
The algorithm which is implemented in this object, instead, is an efficient and parallel
implementation of the Silhouette using the cosine distance measure.
|
Evaluator |
Abstract class for evaluators that compute metrics from predictions.
|
MulticlassClassificationEvaluator |
Evaluator for multiclass classification, which expects input columns: prediction, label,
weight (optional) and probability (only for logLoss).
|
MultilabelClassificationEvaluator |
:: Experimental ::
Evaluator for multi-label classification, which expects two input
columns: prediction and label.
|
RankingEvaluator |
:: Experimental ::
Evaluator for ranking, which expects two input columns: prediction and label.
|
RegressionEvaluator |
Evaluator for regression, which expects input columns prediction, label and
an optional weight column.
|
SquaredEuclideanSilhouette |
SquaredEuclideanSilhouette computes the average of the
Silhouette over all the data of the dataset, which is
a measure of how appropriately the data have been clustered.
