Answer
- C When revealing subtle defects across many edge cases or unusual inputs
- D When migrating an ML system to a new environment, for example from development to production
- E When comparing test results across environments
Explanation
Back-to-back testing is especially useful when an ML system moves, for example from the development to the production environment, and you want to check whether it works the same there. Because very many inputs can be compared, it also finds small deviations that only appear with edge cases or unusual inputs.
