Metrics of the class RankingMetrics, Spark

原文 2016-01-21 08:07:53 0 1 java/ apache-spark/ metrics

I use currently the class RankingMetrics and can calculate the precision . According API of this class, the method for the calculating of recall doesn't exist. Can somebody tell me, where I can find the implementation of recall for Spark Java?

PS I have found also some useful link over all metrics

The recall method exists just with the org.apache.spark.mllib.evaluation.MulticlassMetrics , org.apache.spark.mllib.evaluation.MultilabelMetrics and org.apache.spark.mllib.evaluation.BinaryClassificationMetrics for the moment.

Check the javadoc for MulticlassMetrics , MultilabelMetrics and BinaryClassificationMetrics .
