Your question is Optimize ML Models with Tuning. 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 are working on a supervised learning model that is underperforming and gives inconsistent validation results. The core task is to improve the model through better optimization choices, not to change the business problem.
What is your experience with machine learning model optimization techniques?
