Your question is Data Preprocessing for Reliable Models. 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 preparing data for a supervised learning task and comparing a few candidate models. Before training, you need to decide how to clean, transform, and structure the raw inputs so the model can learn useful patterns.
Discuss the importance of data preprocessing in machine learning.
