Class VotingCombiner

java.lang.Object

org.tribuo.classification.ensemble.VotingCombiner

All Implemented Interfaces:

com.oracle.labs.mlrg.olcut.config.Configurable, com.oracle.labs.mlrg.olcut.provenance.Provenancable<com.oracle.labs.mlrg.olcut.provenance.ConfiguredObjectProvenance>, Serializable, EnsembleCombiner<Label>

public final class VotingCombiner
extends Object
implements EnsembleCombiner<Label>

A combiner which performs a weighted or unweighted vote across the predicted labels.

This uses the most likely prediction from each ensemble member, unlike FullyWeightedVotingCombiner which uses the full distribution of predictions for each ensemble member.
