Synopsis
This operator creates a ROC chart for the given example set and model. The model will be applied on the example set and a ROC chart will be produced afterwards. If you are interested in finding an optimal threshold, the operator
Please note that a predicted label of the given example set will be removed during the application of this operator.
Parameter
- use_example_weights
- Indicates if example weights should be used for calculations (use 1 as weights for each example otherwise). (boolean; default: true)
- use_model
- If checked a given model will be applied for generating ROCChart. If not the examples set must have a predicted label. (boolean; default: true)

- applycount
- The number of times the operator was applied.
- looptime
- The time elapsed since the current loop started.
- time
