Re: BinaryClassificationMetrics only supports AreaUnderPR and AreaUnderROC?

Yeah, for binary data, you can also use MulticlassClassificationEvaluator to evaluate other metrics which BinaryClassificationEvaluator doesn't cover, such as accuracy, f1, weightedPrecision and weightedRecall. Thanks Yanbo On Thu, May 11, 2017 at 10:31 PM, Lan Jiang

BinaryClassificationMetrics only supports AreaUnderPR and AreaUnderROC?

I realized that in the Spark ML, BinaryClassifcationMetrics only supports AreaUnderPR and AreaUnderROC. Why is that? I What if I need other metrics such as F-score, accuracy? I tried to use MulticlassClassificationEvaluator to evaluate other metrics such as Accuracy for a binary classification
