Synopsis
This operator can be used to directly derive a performance measure from a specific data or statistics value.
Description
This operator can be used to derive a specific value of a given example set and provide it as a performance value which can be used for optimization purposes.
Input
- example set: expects: ExampleSet
Output
- performance:
- example set:
Parameters
- performance type: Indicates the way how the macro should be defined.
- statistics: The statistics of the specified attribute which should be used as macro value.
- attribute name: The name of the attribute from which the data should be derived.
- attribute value: The value of the attribute which should be counted.
- example index: The index of the example from which the data should be derived. Negative indices are counted from the end of the data set. Positive counting starts with 1, negative counting with -1.
- optimization direction: Indicates if the performance value should be minimized or maximized.
