Remove Attribute Range
Synopsis
This operator removes a range of attributes from the given ExampleSet.
Description
The Remove Attribute Range operator removes the attributes within the specified range. The first and last attribute of the range are specified by the first attribute and last attribute parameters. All attributes in this range (including first and last attribute) will be removed from the ExampleSet. It is important to note that the attribute range starts from 1. This is a little different from the way attributes are counted in the Table Index where counting starts from 0. So, first and last attributes should be specified carefully.
Differentiation
Select Attributes
Provides a lot of options for selecting desired attributes e.g. on the basis of type, no missing values or even regular expressions.
Remove Correlated Attributes
Selects attributes on the basis of correlations of the attributes.
Remove Useless Attributes
Selects attributes on the basis of usefulness. Different usefulness measures are available e.g. numerical attributes with minimum deviation etc.
Input
example set input
This input port expects an ExampleSet. It is the output of the Retrieve (Deprecated) operator in the attached Example Process. The output of other operators can also be used as input.
Output
example set output
The ExampleSet with selected attributes removed from the original ExampleSet is output of this port.
original
The ExampleSet that was given as input is passed without changing to the output through this port. This is usually used to reuse the same ExampleSet in further operators or to view the ExampleSet in the Results Workspace.
Parameters
first attribute
The first attribute of the attribute range which should be removed is specified through this parameter. The counting of attributes starts from 1.
last attribute
The last attribute of the attribute range which should be removed is specified through this parameter. The counting of attributes starts from 1.
