---------------------------------------------------
Summary: Multiple copies of evaluation statistics printed in
ensemble methods
Key: SAMOA-48
URL: https://issues.apache.org/jira/browse/SAMOA-48
Project: SAMOA
Issue Type: Bug
Components: SAMOA-API
Reporter: Gianmarco De Francisci Morales
When running an ensemble method the evaluation statistics are reported multiple
times. Probably, once per classifier in the ensemble.
We should de-duplicate the output and print the statistics only once.
To reproduce:
{code}
./bin/samoa local target/SAMOA-Local-0.4.0-incubating-SNAPSHOT.jar
"PrequentialEvaluation -l (classifiers.ensemble.Bagging) -s (ArffFileStream -f
../covtypeNorm.arff)"
{code}
{code}
