Course overview
Machine learning enables systems to learn patterns from data and make predictions or decisions without being explicitly programmed for every possible case. It is used in areas such as sales forecasting, customer segmentation, fraud detection, recommendation systems, and risk assessment.
This course introduces the machine-learning workflow, data preparation, exploratory data analysis, feature engineering, supervised and unsupervised learning, regression, classification, clustering, model evaluation, cross-validation, hyperparameter tuning, and responsible model use.
The proposed capstone is an ML Prediction System for a chosen approved use case. It covers dataset preparation, baseline modeling, validation, evaluation, error analysis, documentation, and a professional presentation.
A useful machine-learning model depends on more than algorithm selection. Data quality, representative sampling, appropriate evaluation, leakage prevention, and clear interpretation are essential.

Machine-learning workflow
Machine-learning projects are iterative. Model results, error analysis, deployment constraints, and new data may require returning to data preparation, feature engineering, or evaluation.
Define the goal
