Neural Networks (3Blue1Brown)
by 3Blue1Brown / Grant Sanderson
The most beautiful visual explanation of how neural networks and transformers actually work.
Overview
3Blue1Brown's neural network series is a masterpiece of mathematical animation. It builds intuition for what a neural network is, how gradient descent and backpropagation train it, and — in newer videos — how attention and transformers/LLMs work internally. It won't teach you to code models, but it will give you a mental picture that makes every other resource easier to understand. Free on the site and YouTube.
