Is cross validation automatically implemented in auto model
Studio Operators Performance (Binominal Classification) Performance Binominal Classification (RapidMiner Studio Core) Synopsis This Operator is used to statistically evaluate the strengths and weaknesses of a binary classification, after a trained model has been applied to labelled data. Description
RapidMiner Tutorial (part 5/9) Testing and Training YouTube
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.

Cross validation is the gold standard. It allows you to check your model 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.' Here's why. Cross validation actually splits your data into pieces.

Cross Validation in Practice In this episode, our resident RapidMiner masterminds, Ingo Mierswa & Simon Fischer, spend some quality time together building a cross validation process on Fisher's Iris data set (name pun intended).
Cross Validation process with eReaderadoption — RapidMiner Community
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.
Traintest Split And Cross Validation In Python By Adi Mobile Legends
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)

In this lesson on classification, we introduce the cross-validation method of model evaluation in RapidMiner Studio. Cross-validation ensures a much more rea.
RapidMiner Tutorial How to run a linear regression using cross
As it is true that the Cross Validation operator builds the final model on the whole data set (and thus performs a 11th iteration of the Training subprocess, in case the model port is connected), the Test process is only performed 10 times.
CrossValidation Rules Tips to Optimize your GL eprentise
Cross validation: use this if you want to get the most thoroughly tested models, your data is small, your processes are not very complex so that you can easily embed them in one or multiple nested cross validations, total runtime is not an issue for you, the use case is life-or-death important.

Cross Validation (Concurrency) Synopsis This Operator performs a cross validation to estimate the statistical performance of a learning model. Description. It is mainly used to estimate how accurately a model (learned by a particular learning Operator) will perform in practice. The Cross Validation Operator is a nested Operator.

RapidMiner SVM cross validation and log parameter configuration window
Description. The Bootstrapping 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 also measured during the testing phase.
