Welcome to your interview for the Data Scientist role at System2.
The question is on your right: Improve Predictive Model Accuracy. 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. You have three graded attempts to score 7/10 or better.
You own a predictive model that is missing its accuracy target in validation and in production. The team wants a clear path to improve performance without guessing at fixes.
How would you improve the accuracy of a predictive model?
