Welcome to your interview.
The question is on your right: L1 vs L2 for IoT Telemetry. 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 L1 and L2 regularization. In what scenarios would you choose one over the other for IoT telemetry data?
