Start LearningReviewed July 3, 2026

Overview

This is the modern remake of the course that introduced millions to machine learning. Across three courses you cover linear and logistic regression, neural networks, decision trees, clustering, anomaly detection, recommender systems, and an intro to reinforcement learning — all with Python and scikit-learn/TensorFlow labs. Andrew Ng's teaching is famously clear, making this the default first ML course to recommend. Video content is free to audit; the certificate requires a subscription.
