Welcome to your interview.
The question is on your right: Choosing a Loss Function. 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.
You are discussing model design choices for an AI system and want to explain how you think about training objectives.
What is the loss function you favor most in AI, and why?
