#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
