Synopsis
Uses only a fraction of the data to apply the inner operator on it.Description
This operator works similar to the LearningCurveOperator . In contrast to this, it just splits the ExampleSet according to the parameter "fraction" and learns a model only on the subset. It can be used, for example, in conjunction with GridSearchParameterOptimizationOperator which sets the fraction parameter to values between 0 and 1. The advantage is, that this operator can then be used inside of a XValidation , which delivers more stable result estimations.
Input
