public class PrecisionMetric extends java.lang.Object implements EvaluationMetric
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-
