Example 1 with EnsembleModel

use of org.tribuo.ensemble.EnsembleModel in project tribuo by oracle.

the class StripProvenance method convertModel.

/**
 * Creates a copy of the old model with the requested provenance removed.
 * @param oldModel The model to remove provenance from.
 * @param provenanceHash A hash of the old provenance.
 * @param opt The program options.
 * @param <T> The output type.
 * @return A copy of the model with redacted provenance.
 * @throws InvocationTargetException If the model doesn't expose a copy method (all models should do).
 * @throws IllegalAccessException If the model's copy method is not accessible.
 * @throws NoSuchMethodException If the model's copy method isn't present.
