Class FullyWeightedVotingCombiner

java.lang.Object

org.tribuo.classification.ensemble.FullyWeightedVotingCombiner

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 FullyWeightedVotingCombiner
extends Object
implements EnsembleCombiner<Label>

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

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