Welcome to your interview.
The question is on your right: Batch vs Layer Normalization. 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 difference between batch normalization and layer normalization, and state when you would prefer one over the other.
