Is cross validation automatically implemented in auto model

The Cross Validation Operator is a nested Operator. It has two subprocesses: a Training subprocess and a Testing subprocess. The Training subprocess is used for training a model. The trained model is then applied in the Testing subprocess. The performance of the model is measured during the Testing phase.

In this lesson on classification, we introduce the cross-validation method of model evaluation in RapidMiner Studio. Cross-validation ensures a much more rea.

why is there no 'cross validation' ? — RapidMiner Community

The cross validation allows you to check your models performance on one dataset which you use for training and testing. If you use a cross validation then you are in fact identifying the 'prediction error' and not the 'training error' and here is why. The cross validation splits your data into pieces.

This operator performs a cross-validation in order to evaluate the performance of a feature weighting or selection scheme. It is mainly used for estimating how accurately a scheme will perform in practice. Description The Wrapper-X-Validation operator is a nested operator.

Where in the process to place the 'Cross validation' operator

Often tools only validate the model selection itself, not what happens around the selection. Or worse, they don't support tried and true techniques like cross-validation. This whitepaper discusses the four mandatory components for the correct validation of machine learning models, and how correct model validation works inside RapidMiner Studio.

Split Validation is a way to predict the fit of a model to a hypothetical testing set when an explicit testing set is not available. The Split Validation operator also allows training on one data set and testing on another explicit testing data set. Input training example set (Data Table)

For those that don't know (yet), cross-validation is the de-facto standard approach to evaluate how well predictive models predict - by repeatedly splitting a finite dataset into non-overlapping training and test sets, building a model on a training set, applying it to the corresponding test set, and finally calculating how well it predicts what.
