What is classification in RapidMiner?
Classification is a technique used to predict group membership for data instances. For example, you may wish to use classification to predict whether the train on a particular day will be ‘on time’, ‘late’ or ‘very late’.
What are the different RapidMiner attributes?
These are: id, label, prediction, cluster, weight and batch. Also custom roles can be assigned to Attributes. By default all special Attributes are delivered to the output port irrespective of the conditions in the Select Attribute Operator.

How do you classify a document?
Document classification has two different methods: manual and automatic classification….How does document classification work?
- Supervised method: The classifier is trained on a manually tagged set of documents.
- Unsupervised method: Documents are mathematically organized based on similar words and phrases.

What is cross validation in Rapidminer?
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.
What is split data in Rapidminer?
Description. The Split Data operator takes an ExampleSet as its input and delivers the subsets of that ExampleSet through its output ports. The number of subsets (or partitions) and the relative size of each partition are specified through the partitions parameter. The sum of the ratio of all partitions should be 1.

How do I use the performance (classification) operator?
Then the Performance (Classification) operator is applied on the labeled data to produce a Performance Vector. The Breakpoint is inserted after this subprocess to show this Performance Vector. Note that this model was trained and tested on the same data set (Golf data set), so its accuracy is 100%.
