If you’re new to machine learning, start with a short introduction, then follow a structured beginner course and practise its small coding exercises in a browser. You do not need prior machine-learning knowledge, a powerful computer, or paid software. Basic algebra, statistics, and Python help, but you can fill gaps as you go.
Follow a beginner-friendly course sequence
Google’s recommended foundational sequence gives you a clear route from core ideas to applying them:
- Learn the basic terms. Begin with Google’s Introduction to Machine Learning if concepts such as models and training are unfamiliar.
- Take the Machine Learning Crash Course. Google describes it as a practical introduction with videos, interactive visualizations, and programming exercises. If you are new to ML, Google recommends completing the modules in order; learners who already know some material can use the self-contained modules selectively. Google’s November 12, 2024 announcement described the course at that time as a free, online, 15-hour self-study course with more than 130 exercise questions. Those figures are dated and may no longer describe the current course.
- Continue with problem framing and project management. Google lists Problem Framing and Managing ML Projects as the next foundational courses. These help you think about whether ML suits a problem and how to organize an applied project.
Google’s Machine Learning Crash Course is a sensible starting point for technically minded newcomers who want a guided introduction. Its programming exercises run in Colaboratory, a browser-based environment, so local installation is not necessary to begin.
Prepare only for the parts that need it
Google says no prior ML knowledge is required. Its prerequisites and prework guidance recommends comfort with variables, linear equations, graphs, histograms, means, and basic statistics. Programming ability—ideally Python—is useful for the coding exercises.

#1 Best Overall
- Use scikit-learn to track an example ML project end to end
- Explore several models, including support vector machines, decision trees, random forests, and ensemble methods
- Exploit unsupervised learning techniques such as dimensionality reduction, clustering, and anomaly detection
- Dive into neural net architectures, including convolutional nets, recurrent nets, generative adversarial networks, autoencoders, diffusion models, and transformers
- Use TensorFlow and Keras to build and train neural nets for computer vision, natural language processing, generative models, and deep reinforcement learning
- If algebra or statistics feels rusty: use Google’s linked prework to review the relevant basics. You do not need to finish a long preparation syllabus before opening the introductory course.
- If Python is new: work through the course’s linked Python prework when you reach programming exercises. The same guidance links to preparation for NumPy and pandas.
- If calculus is new: treat it as optional for a first pass. Google says calculus becomes relevant to deeper understanding of advanced topics such as backpropagation.
Start with the concepts you can follow, then pause for targeted preparation when an exercise calls for a skill you lack. This keeps prerequisites from becoming a reason to delay learning altogether.
Learn the machine-learning workflow, not just the vocabulary
Understanding individual terms is useful, but the concepts make more sense when connected to a complete workflow. The official PyTorch beginner tutorial explains: “Most machine learning workflows involve working with data, creating models, optimizing model parameters, and saving the trained models.”
Rank #2
Its step-by-step route covers tensors, data loaders, model building, autograd, optimization, and saving and loading a model. Use it after an introductory course if you want to see how those ideas fit together in code. It is a framework-specific implementation path, rather than a prerequisite for understanding ML concepts.

| Your goal | Next step | What it emphasizes |
|---|---|---|
| Understand core ML ideas and when ML fits a problem | Continue through Google’s foundational courses, including Problem Framing and Managing ML Projects. | Concepts, decisions about applying ML, and project organization. |
| Practise implementing a model | Follow the PyTorch beginner tutorial after, or alongside, introductory study when you are ready to code. | A stepwise workflow using one framework. |
| Keep a detailed practical reference nearby | Consider Aurélien Géron’s Hands-On Machine Learning with Scikit-Learn, Keras, and TensorFlow, 3rd Edition. | O’Reilly classifies this 864-page book as intermediate to advanced; it uses Python examples and is better suited to follow-on study than as a beginner’s required first purchase. |
Google’s free online material is enough to start. A book or framework-specific course is an optional next step chosen for your learning goal, not something you need to buy before beginning.
