What is Brilliant.org?
Brilliant.org is an online learning platform that uses interactive problem-solving to teach STEM subjects. Unlike traditional video-based courses, Brilliant emphasises active learning through guided exercises, simulations, and visual explanations. The Introduction to Neural Networks course specifically covers the foundations of deep learning — from single neurons and activation functions to fully connected networks and backpropagation — all through interactive visualisations that let you see how networks learn in real time.

Tips for Best Results
- Spend 15-20 minutes daily rather than long infrequent sessions — consistency beats intensity
- Complete prerequisite courses (linear algebra basics, probability) first for deeper understanding
- Replay interactive visualisations multiple times — adjust parameters to build intuition
- Use the "Explain" button when stuck rather than skipping ahead
- Pair Brilliant with coding practice (PyTorch or TensorFlow tutorials) to apply what you learn

FAQs
Do I need math background for the neural networks course?
Basic algebra is helpful. The course is designed for beginners and introduces mathematical concepts gradually through visual examples rather than equations.
Is Brilliant better than watching YouTube tutorials?
For building intuition and retaining concepts, yes. Brilliant's interactive approach forces active engagement, which research shows leads to better long-term retention than passive video watching.
Can Brilliant teach me to build real AI models?
Brilliant teaches the conceptual foundations. To build production models, you will need to supplement with hands-on coding courses using frameworks like PyTorch or TensorFlow. Brilliant gives you the "why" — coding courses give you the "how."
How long does the neural networks course take to complete?
Most learners complete it in 2-4 weeks at 15-20 minutes per day. The entire course contains roughly 40-50 interactive lessons.
