Your question is Validate a Machine Learning Model. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
You have trained a model and it looks strong on your holdout set, but the team wants to know whether those results are trustworthy. You need to explain how you would validate the model before it is approved for use.
How do you validate machine learning models?
