In order to stress test a model an operational domain needs to be defined. While operational domains can be manually created, we recommend using the UI and then export the domain as a YAML file.
Here is a very simple domain with a single axis of data variability which specifies the range of expected blur levels:
domains: - name: Example Domain transformations: - name: ChooseImage operator: ChooseImage axes:  - name: Blur operator: Blur axes: - name: blur type: int range: [3, 11] choices:  fixed: False - name: EvaluateSample operator: EvaluateSample axes:  graph: - [ChooseImage, Blur] - [Blur, EvaluateSample]
name: unique name of the operational domain
transformations: list of transformations specifying the axes of data variability
graph: list of edges specifying the computational DAG for the operational domain. Each edge contains two transformation names
[from_transfromation, to_transformation]describing the flow of how the underlying data is processed by the specified transformations.
