Welcome to your interview.
The question is on your right: Class Imbalance in Rare Feature Detection. 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.
How do you address class imbalance when training models to detect rare features in aerial imagery for Nearmap?
