Generate Function Set

Synopsis​

This is an attribute generation operator which generates new attributes by applying a set of selected functions on all attributes.

Description​

This operator applies a set of selected functions on all attributes of the input ExampleSet for generating new attributes. Numerous functions are available including summation, difference, multiplication, division, reciprocal, square root, power, sine, cosine, tangent, arc tangent, absolute, minimum, maximum, ceiling, floor and round. It is important to note that the functions with two arguments will be applied on all possible pairs. For example suppose an ExampleSet with three numerical attributes A, B and C. If the summation function is applied on this ExampleSet then three new attributes will be generated with values A+B, A+C and B+C. Similarly non-commutative functions will be applied on all possible permutations. This is a useful attribute generation operator but if it does not meet your requirements please try the <reference key="operator.generate_attributes">Generate Attributes</reference> operator which is a very powerful attribute generation operator.

Input​

example set input​

This input port expects an ExampleSet. It is the output of the Retrieve operator in the attached Example Process. The output of other operators can also be used as input.

Output​

example set output​

New attributes are created by application of the selected functions and the resultant ExampleSet is delivered through 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.
