Project: build a two-layer network and check its gradients

Bike rides climb with temperature, then fall when it gets too hot, and no straight line can follow. Build the network that can, from scratch in NumPy, and prove its gradients are right.

Lesson overview

Bike rides climb with temperature, then fall when it gets too hot, and no straight line can follow. Build the network that can, from scratch in NumPy, and prove its gradients are right.

What you’ll explore

  • Build a two-layer network by hand, compute its forward pass and gradients, confirm them with a gradient check, and train it with simultaneous updates while reading the loss curve.
