Part V: 1st Pass - Supervised Learning

Supervised learning is the family of ML methods where every training example comes with a known answer: a numeric value for regression tasks or a label for classification tasks. The model learns a mapping from inputs to outputs that generalizes beyond the training examples it saw. In this part you complete your first full inner-loop pass through the CRISP-DM Modeling and Evaluation phases - fitting real models to data, evaluating how well they generalize, and building the practical vocabulary every subsequent part assumes.
