public interface FeatureTransformer extends com.oracle.labs.mlrg.olcut.config.Configurable, com.oracle.labs.mlrg.olcut.provenance.Provenancable<com.oracle.labs.mlrg.olcut.provenance.ConfiguredObjectProvenance>
A feature transformer maps a list of features to a new list of features. Useful for example to apply the hashing trick to a set of features.

Note a list of features returned by a FeatureTransformer may contain duplicate features, and should be reduced to ensure that each feature is unique.
