Foundations
Neural Networks
Neurons, layers, and the forward pass.
You can jump straight in, but this star assumes Linear Algebra. Not recommended as a first stop.
Four layers of depth
Each layer ends with a quiz. Finish layer 4 and you own this concept.
- L1IntuitionWhat a neuron and a network of them actually are, minus the brain metaphor baggage.5m
40 XP - L2MechanicsThe forward pass step by step, common activation functions, and how architecture choices shape what a network can learn.8m
70 XP - L3CodeBuilding a multilayer perceptron from scratch with NumPy, then the idiomatic PyTorch equivalent.12m
110 XP - L4FoundationsForward pass as function composition, backpropagation derived via the chain rule, and why depth causes vanishing/exploding gradients.15m
