The last example parameter is used to set the upper bound of the index range. first_exampleThis parameter is used to set the lower bound of the index range.This is usually used to reuse the same ExampleSet in further operators or to view the ExampleSet in the Results Workspace. The ExampleSet that was given as input is passed without changing to the output through this port.
It is output of the Retrieve operator in the attached Example Process.Ī new ExampleSet including only the examples that are within the specified index range is output of this port. It is also frequently used to filter examples with correct or wrong predictions (usually after testing a learnt model). The Filter Examples operator is frequently used to filter examples that have (or do not have) missing values. Users can also define their own conditions to filter examples.
Several predefined conditions are provided users can select any of them. It takes an ExampleSet as input and returns a new ExampleSet including only those examples that satisfy the specified condition. If you want to filter examples by options other than index range, you may use the Filter Examples operator. The Select Attributes operator is used to select required attributes. This operator may reduce the number of examples in an ExampleSet but it has no effect on the number of attributes. Lower and upper bound of index range are specified using first example and last example parameters. This operator takes an ExampleSet as input and returns a new ExampleSet including only those examples that are within the specified index range. Examples within the specified index range are kept, remaining examples are removed. rows) of an ExampleSet should be kept and which examples should be removed. SynopsisThis operator selects which examples (i.e. You are viewing the RapidMiner Studio documentation for version 9.9 - Check here for latest version Filter Example Range
