Welcome to your interview.
The question is on your right: Generalization Validation Strategy. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
Explain the validation strategy you used in your research or previous role. How did you ensure the model would generalize to unseen real-world environments?
