Instance Attribute Details

#aggregate_classification_metrics ⇒ Google::Apis::BigqueryV2::AggregateClassificationMetrics

Aggregate metrics for classification/classifier models. For multi-class models, the metrics are either macro-averaged or micro-averaged. When macro-averaged, the metrics are calculated for each label and then an unweighted average is taken of those values. When micro-averaged, the metric is calculated globally by counting the total number of correctly predicted rows. Corresponds to the JSON property aggregateClassificationMetrics

Returns:

#confusion_matrix_list ⇒ Array<Google::Apis::BigqueryV2::ConfusionMatrix>

Confusion matrix at different thresholds. Corresponds to the JSON property confusionMatrixList

Returns:
