`auRoc`	`float` Optional. The area under the receiver operating characteristic curve.
`logLoss`	`float` Optional. Logarithmic loss.
`confidenceMetrics`	`List[Dict[str, Any]]` Optional. This is only returned when `only_summary_metrics=False` is passed to evaluate().
`confusionMatrix`	`Dict[str, Any]` Optional. This is only returned when `only_summary_metrics=False` is passed to evaluate().

EvaluationMetric

EvaluationMetric(
    bleu: typing.Optional[float] = None, rougeLSum: typing.Optional[float] = None

The evaluation metric response.

Parameters
Name	Description
`bleu`	`float` Optional. BLEU (Bilingual evauation understudy). Scores based on sacrebleu implementation.
`rougeLSum`	`float` Optional. ROUGE-L (Longest Common Subsequence) scoring at summary level.
