java.lang.Object
org.elasticsearch.client.ml.dataframe.evaluation.classification.PrecisionMetric
- All Implemented Interfaces:
EvaluationMetric,org.elasticsearch.xcontent.ToXContent,org.elasticsearch.xcontent.ToXContentObject
PrecisionMetric is a metric that answers the question:
"What fraction of documents classified as X actually belongs to X?"
for any given class X
equation: precision(X) = TP(X) / (TP(X) + FP(X))
where: TP(X) - number of true positives wrt X
FP(X) - number of false positives wrt X-
