Package org.tribuo.transform

Interface Transformer

All Superinterfaces:

ProtoSerializable<org.tribuo.protos.core.TransformerProto>, Serializable

All Known Implementing Classes:

BinningTransformation.BinningTransformer, SimpleTransform

public interface Transformer
extends ProtoSerializable<org.tribuo.protos.core.TransformerProto>, Serializable

A fitted Transformation which can apply a transform to the input value. Usually contains feature specific information from the training data.

Transformers are serializable, and should only be constructed by their TransformStatistics.
