Split Validation


Synopsis

A SimpleValidation randomly splits up the example set into a training and test set and evaluates the model.


Description

A RandomSplitValidationChain splits up the example set into a training and test set and evaluates the model. The first inner operator must accept an ExampleSet while the second must accept an ExampleSet and the output of the first (which is in most cases a Model) and must produce a PerformanceVector.

This validation operator provides several values which can be logged by means of a ProcessLogOperator. All performance estimation operators of RapidMiner provide access to the average values calculated during the estimation. Since the operator cannot ensure the names of the delivered criteria, the ProcessLog operator can access the values via the generic value names:
