Build job-ready machine learning skills with a free online course in Python—learn models that predict, classify, and cluster data, with exercises and a certificate option.

In this free course, learn about

  • Why learning algorithms scale better than hand-coding rules; core supervised learning framing
  • Linear & logistic regression: cost functions, gradient descent vs Newton’s method optimization
  • Locally weighted regression: instance-weighted local fits and its nonparametric behavior
  • Generative vs discriminative learning: what each models and when to use them
  • Naive Bayes for text: event models (e.g., multinomial vs Bernoulli) and conditional independence
  • SVM optimal margin: constraints, hinge loss intuition, and kernels for non-linear separation
  • Generalization theory: effect of larger hypothesis classes; VC dimension for linear classifiers
  • Practical ML advice: debugging, bias/variance diagnosis, and improving algorithm performance
  • K-means clustering: objective, assignment/update steps, and typical use cases
  • EM algorithm: latent-variable learning via iterative E- and M-steps for complex probabilistic models
  • PCA: dimensionality reduction, variance maximization, and common applications (compression/visualization)
  • MDPs: states, actions, rewards, transitions; fitted value iteration for approximate planning
  • Control topics: finite-horizon LQR and Riccati equation; helicopter controller design workflow; POMDP challenges

Course Description

Machine learning is the skill that turns raw data into decisions: predicting demand, spotting fraud, ranking search results, recommending products, or grouping customers by behavior. This free online course guides you from core principles to practical ways of thinking that modern teams use when building intelligent systems with Python. Instead of treating algorithms as black boxes, you will learn how to reason about model choice, optimization, and generalization so your solutions work beyond a single dataset.

You will develop an intuition for how learning algorithms improve with experience and what it means to balance bias and variance when your model meets real-world noise. Along the way, you explore foundational supervised methods for regression and classification, then progress to probabilistic approaches often used in text and event modeling. You will also connect the dots between decision boundaries and margins, understanding why support vector machines can be powerful and how kernels help models capture non-linear structure without exploding complexity.

A key focus is learning to make models reliable. You will see how expanding the hypothesis space can affect generalization, how complexity measures shape what we can guarantee, and how to think about performance when data is limited. You will also practice unsupervised learning to uncover structure in unlabeled datasets, including clustering to find groups and dimensionality reduction to simplify features while keeping the signal. This mindset is invaluable for cleaning datasets, compressing information, and preparing inputs for downstream models.

The course goes further by introducing sequential decision-making ideas that underpin reinforcement learning. You will learn how Markov decision processes frame control and planning, why partial observability makes policy computation difficult, and how dynamic programming style methods approximate good decisions in large spaces. These topics build a strong conceptual base for applications in robotics, operations, and automated decision systems.

With exercises that reinforce each concept, you will leave with a clearer understanding of the theory behind machine learning and the confidence to apply it in practical programming work. If you are aiming for a career shift, stronger data science fundamentals, or better AI fluency for software projects, this course offers a rigorous path to leveling up while learning at your own pace.
