AI fundamentals
From “what is a model?” to how a chatbot picks its next word — nine hands-on lessons, no maths background needed.
- What learning means
- Getting better, step by step
- Neural networks
- How language models work
Courses
Each course starts with a free module. Every number in every lesson comes from a real dataset or a real model, and every lesson lists its sources.
How AI assistants work
From next-word prediction to the chatbots you use every day: how they are trained, why they make things up, and how to get reliable answers from them.
- From text to prediction
- From predictor to assistant
- Using assistants well
The maths behind AI
Just enough maths to see inside a model: vectors, matrices, derivatives, the chain rule and probability — every idea shown with live, exact calculations.
- Vectors and matrices
- Change and optimisation
- Probability
