Machine Learning Specialization

The updated three-course version is rebuilt in Python and covers the core ground — supervised learning, neural networks, then unsupervised learning, recommenders and a taste of reinforcement learning — with the maths kept approachable. You need comfortable high-school algebra, not a degree.

It is foundations, not job-ready engineering: it will not teach you to build production systems, and it stops short of deep-learning depth. Follow it with hands-on projects or the Deep Learning Specialization. The certificate needs a paid subscription; the free audit covers the learning (as of 2026).

The Machine Learning Specialization is Andrew Ng's updated three-course introduction to machine learning, rebuilt in Python. Most learners finish in about two to three months at a few hours a week. You can audit it free; the certificate runs on Coursera's monthly subscription.
