Traditional programming vs machine learning

Write a hand-made rule for loan approval and a hand-made rule for tomorrow's load; then let a model learn them from data and compare. Concepts: Rules vs learned patterns; data + answers → program Project A: Rule: reject if checking is overdrawn AND duration > 24 months. Compare its Bad recall and cost with a logistic regression. Project B: Rule: tomorrow's hour = same hour last week. Compare its MAE with a linear regression on calendar + temperature.
