Explore how machine learning models make predictions with Google’s Machine Learning Crash Course. Animated explanations, interactive visualisations and practical exercises connect the ideas behind regression, classification and modern AI systems. The course gives you a structured way to move beyond recognising machine learning terminology and start understanding the decisions behind a model.
It is an introduction to machine learning for learners who already have programming and mathematical foundations. You can follow the modules in order to build a broad understanding or revisit selected topics if you have studied them before. The public lessons and browser-based programming exercises provide a free learning route.

What you’ll learn
The course connects model behaviour with the data and evaluation choices behind it:
- Understand prediction models: explore regression, loss, gradient descent and classification.
- Evaluate classification results: consider thresholds and measures such as precision and recall.
- Prepare machine learning data: work through numerical and categorical data concepts.
- Recognise overfitting: examine how datasets and evaluation relate to generalisation.
- Explore modern model ideas: meet neural networks, embeddings and large language models.
- Think beyond training: consider production systems, automated machine learning and fairness.
Skills you’ll gain
- Machine learning fundamentals
- Model evaluation
- Data preparation
- Overfitting awareness
- Neural network concepts
- Responsible model development
Check your foundations before starting
You do not need previous machine learning knowledge, but the course expects comfort with programming, variables, linear equations, graphs and basic statistics. Python is particularly helpful because the programming exercises use it. Basic linear algebra is also useful preparation; calculus background is optional for the more advanced explanations.
The prework includes an introductory machine learning lesson and quick NumPy and pandas tutorials. Use those resources to identify a gap before a notebook becomes frustrating. If loops, collections and functions are unfamiliar, a programming course is a useful first step; Python for Everybody is already in the WikiFree catalogue.
Learn through models, data and experiments
The module sequence begins with prediction models, then develops data preparation and generalisation concepts. Later topics introduce more advanced architectures and the wider concerns involved in real-world systems. Self-contained modules also make it possible to return to a particular concept without repeating the entire course.
The course primarily teaches machine learning concepts. Some exercises use libraries such as NumPy, pandas and Keras, but this is not a detailed training course in every library’s API. That distinction helps you focus on why a modelling choice matters, rather than measuring your progress by the number of functions you can memorise.
For a useful personal study habit, record one question before an exercise and describe the result afterward in ordinary language. When the instructions permit an experiment, change one setting at a time and compare the outcome. This optional approach makes it easier to connect an observable result with the idea the lesson is teaching.
Free exercises and module badges
You can read the public course without a Google account. To run the programming exercises in Colab, sign in with a Google account. Colab is free to use and runs in the browser, so this route does not require purchasing software or a cloud subscription.
Free Colab resources have variable availability and usage limits. Save your work and return later if a free runtime becomes unavailable; unlimited compute is not part of the course offer. Desktop Chrome and Firefox are the browsers most thoroughly tested for the course’s notebook exercises.
Google offers a module badge when you score at least 80% on its end-of-module quiz, with another attempt available if needed. Earned badges appear in a Google for Developers profile. They record learning progress, but Google does not offer formal certification for completing Machine Learning Crash Course.
Frequently asked questions
Is this suitable for a complete programming beginner?
It introduces machine learning, but assumes programming and mathematics foundations. Build those skills first if they are new to you.
Are the programming exercises free?
Yes. They are available in free Colab notebooks with a Google account. Free computing resources remain subject to availability and usage limits.
Does the course include a formal Google certificate?
No. Google offers module badges after the required quiz score, rather than formal certification for the course.
