Merge

Synopsis​

This operator merges two nominal values of the specified regular attribute.

Description​

The Merge operator is used for merging two nominal values of the specified attribute of the input ExampleSet. Please note that this operator can merge only the values of regular attributes. The required regular attribute is specified using the attribute name parameter. The first value parameter is used for specifying the first value to be merged. The second value parameter is used for specifying the second value to be merged. The two values are merged in 'first_second' format where first is the value of the first value parameter and second is the value of the second value parameter. It is not compulsory for the first value and second value parameters to have values from the range of possible values of the selected attribute. However, at least one of the first value and second value parameters should have a value from the range of possible values of the selected attribute. Otherwise this operator will have no affect on the input ExampleSet.
