Overview: Backpropagation
We finally define backpropagation the way we probably should’ve ages ago: as the backward bookkeeping step that tells a neural network which knobs caused the miss. We also connect it to loss, gradients, and gradient descent so the whole training loop actually clicks.

Overview: Gradient Descent
We’re finally giving gradient descent the full couch-table treatment, because it’s hiding under half the AI stories we keep talking about. We get into the hill-climbing mental model, how loss, parameters, and backpropagation fit together, and why the whole thing is the boring engine that actually makes learning happen.
