Prerequisites
Drills
1
Linear Layer (Forward)
Implement a linear layer forward pass — the fundamental building block of every neural network.
Easy🕐 8m⚡ 10 pts
2
Two-Layer Network (Forward)
Chain two linear layers with ReLU to build a complete classifier — input → hidden → output → softmax.
Medium🕐 10m⚡ 15 pts
3
Backpropagation & Training Loop
Compute gradients with the chain rule and train a network on XOR until convergence — the capstone drill.
Hard🕐 15m⚡ 25 pts
