Loop Data Fractions (AI Studio Core)

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

  • example set (IOObject)

    This is an example set input port

Output

  • model (Model)

Parameters

  • fractionThe fraction of examples which shall be used.
  • sampling typeDefines the sampling type (linear = consecutive subsets, shuffled = random subsets, stratified = random subsets with class distribution kept constant)
  • use local random seedIndicates if a local random seed should be used.
  • local random seedSpecifies the local random seed
