MLP Playground — Neuron → Layer → MLP (section 5.1)

The reviewer-panel story from section 5.1, made live. Two inputs (income, credit) flow through two panels of 8 reviewers into one final judge: the 2 → 8 → 8 → 1 network. Every line is a weight, every dot is a tanh(w·x + b) opinion. Drag the inputs, hover anything, or press play.
