Gradient descent is just walking downhill — and why (A − Y) is enough

While building a single neuron from scratch in NumPy for the DLH machine-learning curriculum (classifying MNIST handwritten digits), I kept hearing "gradient descent" as the magic that makes models le…

A neural network is your single neuron, stacked twice — the shapes tell the story

After building a single neuron from scratch in NumPy for the DLH machine-learning curriculum, the next step was the jump that gives "deep" learning its name: stacking two layers instead of one. We wer…
