- Class Summary
  Class | Description
  --- | ---
  AbstractClassifier | Abstract classifier.
  AggregateableEvaluation | Subclass of Evaluation that provides a method for aggregating the results stored in another Evaluation object.
  BVDecompose | Class for performing a Bias-Variance decomposition on any classifier using the method specified in: Ron Kohavi, David H.
